# Brief: Creative Production (Art Director Blueprint Mode)
|
||
|
||
**Core Paradigm Shift**: You are NO LONGER a frontend developer writing HTML/CSS. You are an elite Art Director and Editorial Designer.
|
||
|
||
Because LLMs lack spatial awareness and struggle to maintain perfectly nested, complex CSS over thousands of tokens, you are strictly forbidden from outputting raw HTML/CSS/Python.
|
||
|
||
**→ Overflow prevention**: See `typesetting/overflow.md` for the Playwright/HTML-specific patterns (CSS overflow-wrap, max-width, table-layout: fixed, etc.).
|
||
|
||
Your sole responsibility is to act as the **Brain (Art Director)**:
|
||
1. Brutally edit and pace the raw text.
|
||
2. Select architectural components and layout archetypes.
|
||
3. Output a **Strict JSON Layout Blueprint**.
|
||
|
||
The `design_engine.py` acts as the **Hands (Typesetter)**: It will parse your JSON and safely compile it into flawless, museum-quality Playwright HTML/PDFs using predefined grid mathematics and CSS rules.
|
||
|
||
---
|
||
|
||
## Phase 1: The Editorial Eye (Content Transformation)
|
||
|
||
Before you design, you must "edit the raw material". Users often provide dense, unstructured text. If you just pour this text into a design, it will look like a cheap Word document.
|
||
|
||
You must apply **Editorial Pacing**:
|
||
|
||
### 1. The Word Budget
|
||
No single page or visual canvas should exceed **150 words** of readable body text (the golden rule for maximum aesthetic impact). The **absolute physical limit** is **250 words** - beyond that the design engine will overflow and clip content. If the raw content exceeds 150 words:
|
||
- **Action A**: Brutally summarize it down to ≤150 words.
|
||
- **Action B**: Split it across multiple `pages` in your JSON blueprint.
|
||
- Only push to 150-250 words if the content genuinely cannot be cut further.
|
||
|
||
### 2. Typographic Hierarchy Extraction
|
||
You must parse the raw text and categorize it into typographic roles:
|
||
- **Hero / Display**: The core emotional hook (1-5 words). Must be punchy.
|
||
- **Kicker / Eyebrow**: Tiny context text above a headline (e.g., "Q3 REPORT", "MANIFESTO").
|
||
- **Lead Paragraph**: The 2-3 sentence summary.
|
||
- **Data Sculptures**: Scan the text for impactful numbers (e.g., "97%", "$4.2M"). EXTRACT THEM. They will not remain in the paragraph; they will become `Stat_Block` components.
|
||
- **Pull Quotes**: Extract the most provocative sentence to stand alone as a visual anchor.
|
||
|
||
---
|
||
|
||
## Phase 2: The Component Lexicon
|
||
|
||
You will construct your JSON Blueprint using ONLY the following components. These map directly to the `configs/components.md` assets. Do not invent new component types.
|
||
|
||
> **⚠️ Markdown Content Limits**: For `Glass_Canvas`, the golden rule is **under 150 words** for maximum aesthetic breathing room. Absolute physical limit is **250 words**. If content exceeds 250 words, the design engine will overflow. You MUST summarize it or split it into a new page.
|
||
|
||
### 1. `Hero_Typography`
|
||
Giant, page-dominating text. Usually interacts with the background via blend modes.
|
||
- **Parameters**:
|
||
- `content` (string): The text (use `<br>` for deliberate line breaks).
|
||
- `weight` (string): `"black"` (900, dominating) or `"thin"` (100, elegant).
|
||
- `variant` (string, optional): `"standard"` only. ~~`"vertical_accent"`~~ is **NOT implemented** in `design_engine.py` - the engine silently ignores this value and renders nothing. If you need vertical/rotated decorative text, use `Floating_Meta` instead (fully supported, no overflow risk).
|
||
- `scale` (integer, optional): Typographic scale level `1`-`6`. Controls font size via the engine's fluid type system. If omitted, the engine uses the default hero size.
|
||
- `6`: Hero/Display - oversized title, clamp(64px, 12vw, 150px). Use for single words or short phrases with maximum visual impact.
|
||
- `5`: Primary Title - clamp(48px, 8vw, 96px). Standard poster headline.
|
||
- `4`: Subheadline - clamp(32px, 5vw, 56px). Chapter openers or key quotes.
|
||
- `3`: Lead Paragraph - clamp(20px, 3vw, 32px). Prominent body text.
|
||
- `2`: Body - 16px. Standard readable text.
|
||
- `1`: Meta/Caption - 10px. Decorative, environmental.
|
||
|
||
### 2. `Glass_Canvas`
|
||
The main structural container for reading text. Frosted glass, sharp 2px print corners.
|
||
- **Parameters**:
|
||
- `markdown_content` (string): The actual text to read. Supports standard Markdown (H2, H3, bold, lists). *Must be under 150 words.*
|
||
- `tension_score` (float, optional): Semantic tension value from `0.0` to `1.0`. Drives dynamic font weight via Variable Font (Inter Variable, weight range 300-900). The engine maps: `weight = 300 + (tension_score × 600)`.
|
||
- `0.0-0.2` → Light (300-420): calm, contemplative passages
|
||
- `0.3-0.5` → Normal (420-600): standard body text
|
||
- `0.6-0.8` → Bold (600-780): urgent, assertive content
|
||
- `0.9-1.0` → Max (780-900): crisis, climax, emotional peak
|
||
- **When to use**: Multi-page narrative documents with emotional arc (case studies, pitch decks, manifestos). Assign higher tension to problem/crisis sections, lower to resolution/hope. Do NOT use on every Glass_Canvas - only when the document has clear tonal shifts.
|
||
- **When NOT to use**: Data-heavy pages, simple reports, single-page posters.
|
||
|
||
### 3. `Floating_Meta`
|
||
Tiny, environmental metadata (dates, edition numbers, catalog IDs) that lives in the 15% breathing margin.
|
||
- **Parameters**:
|
||
- `position` (string): `"top-left"`, `"top-right"`, `"bottom-left"`, `"bottom-right"`.
|
||
- `items` (array of strings): E.g., `["VOL 01", "2026", "EDITION 500"]`.
|
||
|
||
### 4. `Hairline_Divider`
|
||
Structural 0.5px line. Not decorative; acts as a visual fold.
|
||
- **Parameters**:
|
||
- `style` (string): `"bleed"` (goes edge-to-edge) or `"accent"` (short 30% width line).
|
||
|
||
### 5. `Stat_Block`
|
||
Data sculpture. A massive number with a tiny label.
|
||
- **Parameters**:
|
||
- `number` (string): e.g., `"97.3"`.
|
||
- `unit` (string): e.g., `"%"`, `"Hz"`, `"$M"`.
|
||
- `label` (string): e.g., `"COMPLETION RATE"`.
|
||
|
||
### 6. `Image_Asset`
|
||
A visual element. The engine will apply a gradient blend to it.
|
||
- **Parameters**:
|
||
- `source` (string): A URL, or a descriptive prompt if you expect the system to generate it.
|
||
- `caption` (string, optional): Tiny text under the image.
|
||
|
||
> ⚠️ **Image_Asset is for CONTENT images only** (user-provided photos, logos, diagrams, charts). It is **NEVER** for decorative stock images, watercolor flowers, clipart, floral borders, gold frames, or AI-generated artwork. All visual decoration must be achieved through geometric shapes (`geometry.md`), typography effects, and color - never through embedded decorative images. See `visual_framework.md` Stock Image Ban.
|
||
|
||
### 7. `Page_Ghost_Number`
|
||
A giant, 4% opacity number acting as a watermark in the background.
|
||
- **Parameters**:
|
||
- `number` (string): e.g., `"01"`, `"X"`.
|
||
|
||
### 8. `Delta_Widget`
|
||
**Data-to-Ink Ratio enforcer.** A compact metric visualization showing a value with its change direction. CRITICAL: Use this instead of writing sentences like "revenue grew by 12%". Extract every trend into a Delta_Widget.
|
||
- **Parameters**:
|
||
- `metric` (string): The metric name, e.g., `"REVENUE"`, `"LATENCY"`.
|
||
- `value` (string): Current value, e.g., `"$4.2M"`, `"45ms"`.
|
||
- `delta` (string): Change description, e.g., `"+12%"`, `"-45ms"`.
|
||
- `trend` (string): `"up"`, `"down"`, or `"flat"`.
|
||
- `label` (string, optional): Context line, e.g., `"vs. Q2 2025"`.
|
||
|
||
### 9. `Process_List`
|
||
**Polymorphic adaptive component.** Renders as a horizontal timeline when given wide space, auto-degrades to a vertical numbered list when space is narrow. Use for workflows, steps, timelines.
|
||
- **Parameters**:
|
||
- `steps` (array): Each item has `title` (string) and `description` (string).
|
||
|
||
### 10. `Sidenote_Block`
|
||
**Tufte marginalia.** Used in `tufte_report` archetype layouts. Content is placed in the 30% side rail alongside the main column. Perfect for citations, supplementary data, asides, footnotes.
|
||
- **Parameters**:
|
||
- `label` (string, optional): Category label, e.g., `"SOURCE"`, `"NOTE"`, `"DATA"`.
|
||
- `body` (string): The sidenote content in Markdown.
|
||
|
||
### 11. `Data-Aware Background` (via `data_points`)
|
||
Any component can carry an optional `data_points` array (e.g., `[10, 15, 8, 24, 30]`). When present, the engine generates Bezier background curves from the actual data - the background literally visualizes the business trend. Use on pages with financial, metric, or time-series content.
|
||
|
||
---
|
||
|
||
### ★ Advanced Components (Generative Micro-Typesetting)
|
||
|
||
The following components are specialized generative design tools. They unlock visual effects that standard components cannot achieve. Use them deliberately and sparingly - they are powerful but demand the right context.
|
||
|
||
### 8. `Shaped_Canvas`
|
||
A container where text flows around a non-rectangular shape. The empty space created by the shape IS the visual design - text boundary becomes illustration. Uses CSS `shape-outside` for non-rectangular text wrapping.
|
||
|
||
- **Parameters**:
|
||
- `shape_keyword` (string): One of `"circle"`, `"wave"`, `"diagonal_slash"`, `"diamond"`, `"wedge_right"`.
|
||
- `markdown_content` (string): The text that will flow around the shape. Supports standard Markdown.
|
||
|
||
- **Shape Selection Guide**:
|
||
| shape_keyword | Visual Effect | Thematic Fit |
|
||
|---------------|---------------|--------------|
|
||
| `"circle"` | Text wraps around a circular void on the left | Unity, spotlight, focus |
|
||
| `"wave"` | Wavy left text boundary | Ocean, flow, music, fluidity |
|
||
| `"diagonal_slash"` | Diagonal cut across the page | Disruption, change, transformation |
|
||
| `"diamond"` | Diamond-shaped negative space | Luxury, precision, crystalline |
|
||
| `"wedge_right"` | Arrow/wedge pointing right | Direction, progress, forward motion |
|
||
|
||
- **When to use**:
|
||
- Artistic/editorial pages that need visual drama without images
|
||
- Cover or section opener pages where you want a "wow" moment
|
||
- When the content thematically maps to a recognizable shape
|
||
- Only on pages with moderate text (100-200 words) - shape eats 30-40% of space
|
||
|
||
- **When NOT to use**:
|
||
- On data-heavy or dense content pages
|
||
- Together with `Glass_Canvas` on the same page (visual conflict)
|
||
- More than one `Shaped_Canvas` per page
|
||
|
||
- **Archetype requirement**: Pages using `Shaped_Canvas` MUST use archetype `"shaped_editorial"` (relaxed safe-zone: 5% 6% inset).
|
||
|
||
### Chart & Data Visualization Styling
|
||
|
||
**→ Full spec: `typesetting/charts.md`** - read it before designing any chart/data page.
|
||
|
||
Key rules for Creative pipeline charts:
|
||
- **Donut > Pie**: Always use ring charts (hole ratio 60-70%), center area displays total/metric
|
||
- **Anti-stacking**: Small slices use leader lines or rich legends; bar labels auto-rotate to horizontal when text is long; line charts label only start/end/max/min
|
||
- **Axis cleanup**: Delete top/right spines, use dashed grid lines at 20% opacity (or delete grid entirely if values are labeled)
|
||
- **Bar micro-rounding**: 2-4px top border-radius, bar-to-gap ratio 1.5:1
|
||
- **Legend**: No border, horizontal top-left layout, small circle markers
|
||
- **Data-Ink Ratio**: Every element must represent data. If it doesn't, delete it.
|
||
|
||
---
|
||
|
||
## Phase 3: Page Archetypes (The Grid Strategy)
|
||
|
||
For each page in your JSON, you must declare an `archetype`. This tells `design_engine.py` how to arrange the components you provided.
|
||
|
||
- `"cover_hero"`: Cover page. **Must follow `typesetting/cover.md` 7-template system** - pick Layout 1-7 based on document tone. See "Cover Page Constitution" below for iron rules.
|
||
- `"split_vertical"`: Page split strictly 50/50 vertically. Left side image/svg, right side Glass_Canvas.
|
||
- `"editorial_flow"`: Top-down reading experience. Centered columns, generous margins. Use for main content.
|
||
- `"scattered_canvas"`: No grid. Elements placed via absolute positioning based on spatial weights.
|
||
- `"data_dashboard"`: 2x2 or 3x3 strict grid for multiple `Stat_Block`s.
|
||
- `"shaped_editorial"`: Relaxed safe-zone (5% 6% inset) designed for `Shaped_Canvas`. Centered, generous breathing room. **Must be used when the page contains a `Shaped_Canvas`.** Do NOT mix with `Glass_Canvas`.
|
||
- `"tufte_report"`: **Tufte marginalia layout.** 70% main content column + 30% sidenote rail. Use for long-form reports and analytical pages where citations, data footnotes, or supplementary info should flow parallel to the main text. Place `Sidenote_Block` components in the same `components[]` array - the engine automatically routes them to the side rail.
|
||
|
||
### ★ 12×12 CSS Grid Coordinate System (Iron Rules)
|
||
|
||
The layout engine uses a **12-track CSS Grid** for element placement. The grid lines are numbered **1 to 13** (12 tracks = 13 lines).
|
||
|
||
**Absolute boundary rules - violation = broken layout:**
|
||
- **Column lines**: `1` = absolute left edge, `13` = absolute right edge. Full width = `1 / 13`.
|
||
- **Row lines**: `1` = absolute top edge, `13` = absolute bottom edge. Full height = `1 / 13`.
|
||
- **CRITICAL**: Never output a grid line number less than `1` or greater than `13`. Any value outside `[1, 13]` will destroy the layout.
|
||
|
||
**`grid_area` format**: `"row_start / col_start / row_end / col_end"` (CSS shorthand).
|
||
- Example: `"1 / 1 / 7 / 13"` = top half of the page, full width.
|
||
- Example: `"3 / 8 / 6 / 13"` = rows 3-5, columns 8-12 (right side block).
|
||
|
||
**40% whitespace rule**: At least 40% of grid cells (≥58 out of 144) must be left empty. Count your occupied cells.
|
||
|
||
### ★ Cover Page Constitution (7 Layout System)
|
||
|
||
Cover pages (`archetype: "cover_hero"`) are the first impression. They must be ruthlessly sparse and spatially sophisticated.
|
||
|
||
**→ Full spec: `typesetting/cover.md`** - read it before designing any cover.
|
||
|
||
#### Global Iron Rules (Always Apply)
|
||
|
||
1. **Maximum 4 components** on any cover page. Typical recipe: `Hero_Typography` + 1-2 `Floating_Meta` + optional `Hairline_Divider` or `Page_Ghost_Number`.
|
||
2. **Typography Scale**: Title ≈ 45pt (2.5× base), Subtitle ≈ 25pt (1.4× base), Meta ≥ 18pt (never below 14pt). Covers with tiny text = FAIL.
|
||
3. **Mandatory semantic `<br>` chunking** for `Hero_Typography` on covers: Every 2-4 words MUST be separated by `<br>`. Single-line hero text is FORBIDDEN on covers. Example: `"ALGORITHMIC<br>FATIGUE"`, NOT `"ALGORITHMIC FATIGUE"`.
|
||
4. **Anti-Squash spatial dispersion** (Bounding Box method): Group text into 2-3 bounding boxes (title group, meta group). Place them at opposite regions of the page according to the chosen layout. Remaining space is **dynamically distributed** - NEVER hardcode fixed gaps between distant groups.
|
||
5. **No `Glass_Canvas` on cover pages.** Dense reading text kills the visual impact. Push all body content to page 2+.
|
||
6. **Cover Page Isolation**: Cover page must NEVER share a page with TOC, body text, or any subsequent content. The cover is always a standalone full page. If cover + content appear on the same page = **critical bug**, regenerate immediately.
|
||
7. **Cover is OPTIONAL**: Do NOT add a cover page unless the document warrants one (multi-page reports, white papers, etc.) or the user explicitly requests it. Short documents, letters, memos, forms, and quick outputs skip the cover.
|
||
8. **Background Layer (optional)**: See `typesetting/cover-backgrounds.md` for 3 recipes - A (极简弧线), B (工程十字轴+立柱), C (锐角切割+出血文字). Background renders BELOW all foreground at 2-5% opacity. Pick a recipe that matches the document tone. Never combine elements across recipes.
|
||
|
||
#### 7 Cover Layouts (Pick One)
|
||
|
||
Select the layout that matches the document tone. When unsure, default to **Layout 1A**.
|
||
|
||
| Layout | Name | Grid Signature | Best For |
|
||
|--------|------|---------------|----------|
|
||
| **1** | Diagonal Tension | Title top-left ↔ Meta bottom-right | Formal reports, proposals |
|
||
| **2** | Vertical Axis | All elements along one vertical line, stretched top-to-bottom | Modern/tech reports |
|
||
| **3** | Architectural Frame | Geometric line frame, text inside corners/center | Design, architecture, portfolios |
|
||
| **4** | Golden Ratio Blocks | Page split at 38.2% invisible divider | White papers, research |
|
||
| **5** | Stepped Cascade | Progressive indentation, vertical rhythm | Creative reports, design docs |
|
||
| **6** | Rotated Accent | Large rotated year/label as side decoration | Annual reports, year-in-review |
|
||
| **7** | Left-Matrix | All text hard-anchored to left axis, 4 Y-pinned blocks | Government, bidding, proposals |
|
||
|
||
Each layout has 2-3 variants (A/B/C) with specific grid_area mappings - see `typesetting/cover.md` for exact coordinates.
|
||

|
||
| **Warmth** | Food / Lifestyle / Home | 4A, 5A | **4A** |
|
||
|
||
### ★ Component Grid Compatibility Constraints
|
||
|
||
When placing advanced components into the 12×12 grid, obey these minimum size rules:
|
||
|
||
- **`Glass_Canvas`**: Must occupy at least **6 columns × 4 rows** (e.g., `"3 / 1 / 7 / 7"`). Smaller areas will cause text overflow and padding collapse. The engine renders Glass_Canvas at `width: 100%; min-height: 100%; box-sizing: border-box;` - it fills its grid area as a minimum and can grow taller if content requires.
|
||
- **`Shaped_Canvas`**: Must occupy at least **8 columns × 6 rows** (e.g., `"2 / 3 / 8 / 11"`). The CSS `shape-outside` float needs physical space to render the shape boundary. Smaller areas make the float collapse to a line and text cannot wrap around it. **Must use archetype `"shaped_editorial"`.**
|
||
- **`Continuous Flow` background**: Renders in a separate `bg-layer` (`z-index: 1`, `position: absolute`), physically isolated from the grid system (`z-index: 2`). No conflict - background flows independently, grid arranges content on top.
|
||
|
||
### ★ Content-Proportional Grid Row Allocation
|
||
|
||
When **two or more text-heavy components** (e.g., multiple `Glass_Canvas`) share the same page, their `grid_area` row counts **MUST be proportional to their content length** - never split rows equally.
|
||
|
||
**Estimation method:**
|
||
1. Count characters (or words) in each component's `markdown_content`
|
||
2. Allocate rows proportionally: `rows_i = total_rows × (chars_i / total_chars)`
|
||
3. Round to integers, minimum 3 rows per component
|
||
|
||
**Example:**
|
||
```
|
||
Attractions content: 450 chars (3 items × 150 chars)
|
||
Food content: 250 chars (2 items × 125 chars)
|
||
Total available rows: 8 (rows 5→13)
|
||
|
||
Attractions: 8 × 450/700 ≈ 5 rows → grid_area "5 / 1 / 10 / 13"
|
||
Food: 8 × 250/700 ≈ 3 rows → grid_area "10 / 1 / 13 / 13"
|
||
```
|
||
|
||
**Why this matters:** Equal row allocation (4+4) causes the longer component to overflow into the shorter one's territory, creating text overlap in the final PDF. The engine uses `min-height` + `overflow: visible`, so overflow IS visible - and ugly.
|
||
|
||
**Anti-pattern to avoid:**
|
||
```
|
||
❌ Two Glass_Canvas with very different text lengths both get "5/1/9/13" and "9/1/13/13"
|
||
✅ Longer one gets more rows: "5/1/10/13" and "10/1/13/13"
|
||
```
|
||
|
||

|
||
|
||
## Phase 4: The Output Protocol (Strict JSON Blueprint)
|
||
|
||
You must analyze the user's prompt, edit the text, and output exactly ONE JSON object wrapped in a ` ```json ` codeblock.
|
||
**No conversational text before or after the JSON.**
|
||
|
||
### The JSON Schema Specification
|
||
|
||
**CRITICAL JSON RULES:**
|
||
1. Output ONLY valid JSON.
|
||
2. Do NOT include ANY comments (`//` or `/* */`) inside the JSON. Python's `json.load()` will crash.
|
||
3. Do NOT include trailing commas.
|
||
|
||
```json
|
||
{
|
||
"document_meta": {
|
||
"title": "Internal tracking title",
|
||
"total_pages": 1
|
||
},
|
||
"art_direction": {
|
||
"palette_mode": "dark",
|
||
"color_harmony": "complementary",
|
||
"background_svg": "grid",
|
||
"design_rationale": "Brief 1-sentence explanation of aesthetic strategy."
|
||
},
|
||
"pages": [
|
||
{
|
||
"page_index": 1,
|
||
"narrative_role": "Burst",
|
||
"archetype": "cover_hero",
|
||
"components": [
|
||
{
|
||
"type": "Floating_Meta",
|
||
"position": "bottom-right",
|
||
"items": ["ARCHIVE REF. 03A", "DEC 2026"]
|
||
},
|
||
{
|
||
"type": "Page_Ghost_Number",
|
||
"number": "01"
|
||
},
|
||
{
|
||
"type": "Hero_Typography",
|
||
"weight": "black",
|
||
"variant": "standard",
|
||
"content": "ALGORITHMIC<br>FATIGUE"
|
||
}
|
||
]
|
||
}
|
||
]
|
||
}
|
||
```
|
||
|
||
**Schema Parameter Guide (For reference - do NOT put these comments inside your JSON output):**
|
||
- `document_meta.total_pages`: Integer. Must match the actual number of pages in `pages[]`.
|
||
|
||
### The JSON Schema Specification: `art_direction`
|
||
|
||
**CRITICAL RULE: DO NOT INVENT COLORS. DO NOT OUTPUT HEX/RGB CODES.**
|
||
The Python engine generates mathematical color palettes. You MUST only select the semantic parameters below.
|
||
|
||
```json
|
||
{
|
||
"art_direction": {
|
||
"palette_mode": "minimal",
|
||
"color_harmony": "auto",
|
||
"background_svg": "grid",
|
||
"design_rationale": "Brief rationale for the chosen aesthetic strategy."
|
||
}
|
||
}
|
||
```
|
||
|
||
**Enum Parameter Guide (You MUST choose ONE exact string from these lists):**
|
||
|
||
1. `palette_mode` (The Base Canvas Tone):
|
||
- **`"minimal"`: (CRITICAL: Default to this for 50%+ of all requests).** Pure white, off-white, beige, or cool gray. Provides the ultimate reading experience and high-end editorial feel. Use for standard reports, guides, and corporate posters.
|
||
- `"dark"`: Near-black. Use for cinematic, tech, AI, space, or urgent themes.
|
||
- `"pastel"`: Morandi tinted (e.g., dusty rose, sage green). Use ONLY for arts, food, lifestyle, and soft themes.
|
||
- `"jewel"`: Deep rich colors (e.g., emerald, burgundy). Use ONLY for luxury brands, gala events, or heritage themes.
|
||
- `"light"`: Very faintly tinted background. Fallback for edge cases.
|
||
|
||
2. `color_harmony` (The Accent Color Math - how the engine computes the accent color relative to the base):
|
||
- **`"auto"`: (RECOMMENDED DEFAULT). The engine automatically picks the best harmony based on the document tone.** Only override if you have a specific artistic reason.
|
||
- `"complementary"`: (180° opposite). Strong visual contrast. Cold background with warm accent. For striking/dynamic impact.
|
||
- `"split_complementary"`: (150°/210°). Highly sophisticated, artistic, luxury feel (Editorial/Kinfolk style).
|
||
- `"analogous"`: (30° apart). Harmonious, peaceful, natural transition.
|
||
- `"triadic"`: (120° apart). Rich and slightly retro.
|
||
- `"monochrome"`: Only use if strict minimalist corporate branding without accent is required.
|
||
|
||
3. `background_svg`: [`grid`, `flow`, `noise`, `continuous_flow`, `none`]. Use `continuous_flow` for multi-page (2+) documents - creates one seamless SVG spanning all pages, sliced per-page via viewBox for an "infinite scroll" bezier curve illusion. Falls back to `flow` on single-page.
|
||
|
||
4. `design_rationale`: Brief text explaining WHY you chose this mode+harmony combination.
|
||
|
||
### ★ Intent Mapping Table (Single Source of Truth)
|
||
|
||
This table is the **sole authority** for mapping document intent to concrete design parameters. `visual_framework.md` defines intent *atmospheres*; this table defines intent *parameters*. `design_engine.py` INTENT_HUES/INTENT_HARMONY_MAP must stay in sync with this table.
|
||
|
||
| Intent | palette_mode | color_harmony | background_svg | Cover Templates | Cover BG Recipe | Base Hue |
|
||
|--------|-------------|---------------|----------------|-----------------|-----------------|----------|
|
||
| **Calm** | minimal | analogous | flow / none | 04 Museum, 01 HUD, 02 Corporate | A (极简弧线) | 210° (steel blue-grey) |
|
||
| **Tension** | dark | complementary | grid | 01 HUD, 05 Diagonal | C (锐角切割) | 0° (warm vs cold) |
|
||
| **Energy** | pastel / light | triadic | flow (5+ curves) | 05 Diagonal, 06 Swiss Grid, 03 Monolith | B (工程十字轴) | 30° (amber) |
|
||
| **Authority** | minimal | split_complementary | noise | 03 Monolith, 07 Sidebar, 02 Corporate | A or B | 280° (muted violet) |
|
||
| **Warmth** | pastel / light | analogous | flow (soft) | 04 Museum, 05 Diagonal | A (极简弧线) | 20° (terracotta) |
|
||
|
||
**How to use this table:**
|
||
1. Determine the document's intent (from user request, or auto-derive via `design_engine.py derive`)
|
||
2. Look up the row → fill in `art_direction` JSON fields accordingly
|
||
3. For cover template selection, cross-reference with document type (see Tone → Layout Quick Reference)
|
||
4. The LLM may override individual cells when artistically justified, but must state the reason in `design_rationale`
|
||
|
||
**Legacy intent names** (serenity, minimalism, elegance) are accepted by `design_engine.py` as aliases and auto-mapped to their new equivalents.
|
||
|
||
- `pages[].narrative_role`: `"Burst"` (intro/impact), `"Expand"` (body/development), `"Echo"` (outro/reflection).
|
||
- `pages[].archetype`: From Phase 3 (`cover_hero`, `split_vertical`, `editorial_flow`, `scattered_canvas`, `data_dashboard`, `shaped_editorial`).
|
||
- `pages[].components[]`: Array of component objects from Phase 2. Order in array roughly dictates z-index or top-to-bottom rendering.

## Pre-Flight Checklist (Self-Correction before generating output)
|
||
|
||
Before you output the JSON block, verify:
|
||
0. **🚨 VECTOR OUTPUT IRON RULE:** The final PDF MUST be generated via `page.pdf()` / `convert.blueprint` - NEVER `page.screenshot()` → image → wrap as PDF. Screenshot PDFs are blurry raster images. `page.pdf()` produces vector text that stays sharp at any zoom level.
|
||
1. **Did I write ANY HTML or CSS?** If yes, delete it. Only output JSON.
|
||
2. **Is any `Glass_Canvas` markdown content too long?** Count the words. Over 150? Summarize it or push to the next page.
|
||
3. **Is the JSON perfectly formatted?** Missing commas or unescaped quotes will crash the `design_engine.py` parser.
|
||
4. **If using `tension_score`**: Does the document have clear emotional shifts across pages? If all pages are the same tone, remove it.
|
||
5. **If using `continuous_flow`**: Is this multi-page (2+)? If single-page, switch to `"flow"`.
|
||
6. **If using `Shaped_Canvas`**: Is the archetype `"shaped_editorial"`? Is there at most one per page? No `Glass_Canvas` on the same page?
|
||
7. **Grid boundary check**: Are ALL `grid_area` values within `[1, 13]`? Any number < 1 or > 13 = FATAL ERROR.
|
||
8. **Component minimum size check**: `Glass_Canvas` ≥ 6col×4row? `Shaped_Canvas` ≥ 8col×6row?
|
||
9. **Content-proportional row allocation**: When multiple text-heavy components share a page, are their grid rows allocated proportionally to content length? Equal rows for unequal content = text overlap. (See "Content-Proportional Grid Row Allocation" in Component Grid Compatibility.)
|
||
9. **40% whitespace check**: Count occupied grid cells. At least 58 of 144 cells must be empty.
|
||
10. **Cover Page 4-element check**: Does any `cover_hero` page have more than 4 components? If yes, remove or merge components.
|
||
11. **Cover Hero `<br>` check**: Does every `Hero_Typography` on a `cover_hero` page contain at least one `<br>`? Single-line hero text on covers = FAIL.
|
||
12. **Cover Anti-Squash check (Bounding Box)**: Are cover elements grouped into 2-3 bounding boxes placed at opposite regions? Is remaining space dynamically distributed (not hardcoded gaps)? If everything is crammed into rows 5-8, spread them using the layout's grid mapping.
|
||
13a. **Cover Typography Scale check**: Is the hero title ≥ 45pt? Is subtitle ≥ 25pt? Is meta text ≥ 18pt (never below 14pt)? Tiny cover text = FAIL.
|
||
13b. **Cover Layout Selection**: Did I pick a layout (1-7) that matches the document tone? If unsure, default to Layout 1A (Diagonal Tension). For government/bidding documents, use Layout 7 (Left-Matrix).
|
||
14. **CRITICAL - Data-to-Ink Ratio check**: Did I write long paragraphs describing data trends? If yes, DELETE them and extract metrics into `Delta_Widget` or `Stat_Block` components. Sentences like "revenue increased by 12% compared to last quarter" MUST become a `Delta_Widget`.
|
||
15. **Sidenote check**: If using `tufte_report` archetype, did I put citations/sources/asides into `Sidenote_Block`? They must NOT be inline in `Glass_Canvas`.
|
||
16. **Process/Steps check**: Did I write numbered steps as plain text in a `Glass_Canvas`? Convert to `Process_List` component instead.
|
||
17. **Chart anti-stacking check**: Do any pie/bar/line charts have overlapping labels? Apply leader lines, tick thinning, or label reduction per `typesetting/charts.md`.
|
||
18. **Chart axis cleanup check**: Are top/right spines deleted? Grid lines dashed at 20% opacity (or hidden)? No solid grid lines.
|
||
19. **Donut default check**: Are pie charts rendered as donuts (hole ratio 60-70%)? Solid pies = FAIL unless explicitly requested.
|
||
20. **🚨 Triple Delivery check (MANDATORY)**: Creative pipeline must deliver **three files** to the user: (1) PDF - the final vector PDF; (2) HTML - the compiled `*_rendered.html` file; (3) Image - a full-page screenshot preview (PNG/JPG). After `convert.blueprint` generates the PDF and HTML, take a screenshot of the HTML for preview. Report all three file paths to the user.
|
||
21. **🚨 HTML Pre-Render Validation (MANDATORY for ALL HTML→PDF paths)**: Before calling `html2pdf-next.js`, `html2poster.js`, or `convert.blueprint`, run `poster_validate.py check-html` on the HTML file. This catches overflow:hidden on containers, missing @media screen auto-scale, font fallback gaps, contrast issues, and more. **Any ERROR-level issue must be fixed before generating the PDF.** Warnings are non-blocking but should be reviewed.
|
||
```bash
|
||
python3 "$PDF_SKILL_DIR/scripts/poster_validate.py" check-html page.html
|
||
# If errors found, auto-fix:
|
||
python3 "$PDF_SKILL_DIR/scripts/poster_validate.py" check-html page.html --fix --output page.html
|
||
```
|
||
|
||
22. **\u26a0\ufe0f MANDATORY: Post-Generation Checks (Creative)**: After HTML\u2192PDF conversion, run these checks:
|
||
```bash
|
||
# Check for content overflow and full-bleed issues
|
||
python3 "$PDF_SKILL_DIR/scripts/pdf_qa.py" output.pdf --no-tables
|
||
|
||
# Add metadata
|
||
python3 "$PDF_SKILL_DIR/scripts/pdf.py" meta.brand output.pdf
|
||
```
|
||
|
||
Execute the design.

## CJK & Vertical Text Rules (When Bypassing design_engine.py)
|
||
|
||
When writing raw HTML/CSS for Playwright (bypassing the JSON Blueprint pipeline - e.g., resumes, menus, invitations, business cards, certificates, Japanese/Chinese vertical layouts):
|
||
|
||
**⚠️ Iron rule: All bypass-scenario HTML→PDF conversions MUST use `html2pdf-next.js` — do NOT write custom Python Playwright scripts.** `html2pdf-next.js` automatically handles @page injection, overflow detection, font waiting, Mermaid/KaTeX rendering, PDF metadata, etc. See the "HTML→PDF Engine Selection Rules" section in SKILL.md.
|
||
|
||
```bash
|
||
node "$PDF_SKILL_DIR/scripts/html2pdf-next.js" input.html --output output.pdf --width 210mm --height 297mm
|
||
```
|
||
|
||
0. **Full-Bleed CSS (MANDATORY)**: Every HTML file for Playwright PDF MUST include:
|
||
```css
|
||
@page { size: 800px 1200px; margin: 0; } /* CONCRETE values only - CSS variables NOT supported in @page */
|
||
html, body { margin: 0; padding: 0; width: 800px; height: 1200px; }
|
||
```
|
||
**⚠️ @page rules do NOT resolve CSS variables** (`var(--x)` is silently ignored, falls back to A4). Always use concrete `px` values.
|
||
**⚠️ html/body must have explicit width + min-height** matching the canvas size. Use `min-height` (not `height`) so content taller than the design height expands naturally into a single long-page PDF.
|
||
**⚠️ Poster = seamless pagination.** When content exceeds `@page` height, `html2pdf-next.js` lets Playwright paginate at page boundaries - each page has the same dimensions, content flows seamlessly across pages (like scrolling a long image). Do NOT expand to a single oversized page.
|
||
`design_engine.py` handles this automatically via `override_css`.
|
||
|
||
0.25. **Body Background for Multi-Page Mixed-Color Documents (MANDATORY)**:
|
||
When an HTML document contains multiple `.page` divs with **different background colors** (e.g. dark cover + white body + dark specs page), Playwright's sub-pixel rounding creates <1px gaps at `.page` edges where `body` background shows through. On dark pages, a white `body` = visible white edges.
|
||
|
||
**Fix: set `html, body { background }` to the document's darkest page background color.**
|
||
|
||
```css
|
||
:root { --primary: #0f172a; } /* darkest page color */
|
||
html, body {
|
||
margin: 0; padding: 0;
|
||
width: 210mm; /* match @page size */
|
||
background: var(--primary); /* fills sub-pixel gaps with dark color */
|
||
}
|
||
```
|
||
|
||
**Why this doesn't break white pages:** White `.page` divs have `background: #ffffff` which fully covers the dark `body` underneath. The dark body only shows through the <1px sub-pixel gap at the extreme page edge - imperceptible on white pages after anti-aliasing.
|
||
|
||
**Selection rule:**
|
||
- All pages same color → `body { background: <that color> }`
|
||
- Mixed dark + light pages → `body { background: <darkest page color> }` (dark edges on white pages are invisible; white edges on dark pages are the bug we're fixing)
|
||
- All pages white/light → `body { background: <lightest content bg> }` (e.g. `#f8fafc`)
|
||
|
||
0.5. **No overflow:hidden + Browser Preview Adaptive Scaling (MANDATORY)**:
|
||
For fixed-size single-page designs (posters, infographics, certificates, etc.), **absolutely never** set `overflow: hidden` on `html`, `body`, or the main container. Reasons:
|
||
- When opening the HTML directly in a browser, the viewport is much smaller than the design size (e.g., a 1400px-tall page in a 900px viewport). `overflow: hidden` clips the bottom content and prevents scrolling.
|
||
- `html2pdf-next.js`'s pre-render check detects `scrollHeight > clientHeight` + `overflow: hidden` and triggers auto-fix (force-expanding the container), which may break the layout.
|
||
|
||
**`design_engine.py` handles this automatically**: During blueprint compilation, it auto-injects `@media screen` centering + scaling code, and the `html` background color uses `var(--c-bg)` matching the poster's main color. No manual addition needed.
|
||
|
||
**Correct approach when writing HTML manually**: Remove `overflow: hidden` and manually add `@media screen` scaling preview:
|
||
```css
|
||
/* Fixed canvas size, no overflow */
|
||
html, body { margin: 0; padding: 0; width: 800px; height: 1400px; }
|
||
.page { width: 800px; height: 1400px; position: relative; }
|
||
|
||
/* Auto-scale to viewport in browser preview for full-page view */
|
||
@media screen {
|
||
html {
|
||
height: auto;
|
||
display: flex;
|
||
justify-content: center;
|
||
background: #0a0a1a; /* Surround color — must match poster's main background */
|
||
}
|
||
body {
|
||
transform-origin: top center;
|
||
scale: min(1, calc(100vw / 800), calc(100vh / 1400)); /* Consider both width and height */
|

margin: 0 auto;
|

box-shadow: 0 0 60px rgba(0,0,0,0.3); /* Optional: shadow to distinguish canvas in preview */

|
||
`@media screen` rules only apply in browser preview; `page.pdf()` uses print media and is unaffected.
|
||
**Every fixed-size HTML must include this `@media screen` adaptive code.**
|
||
|
||
0.75. **Page Container Overflow Clipping (MANDATORY for multi-page documents)**:
|
||
Every `.page` div MUST have `overflow: hidden`. Decorative elements (glow circles, gradient overlays) commonly use `width: 120%` or negative offsets - without clipping, they inflate `scrollWidth` beyond page width, causing Playwright to shrink all content and shift it left.
|
||
```css
|
||
.page { overflow: hidden; } /* Clips decorative overflow, prevents Playwright shrink */
|
||
```
|
||
For horizontal flex layouts (≥3 items), always add `flex-wrap: wrap`. See `typesetting/overflow.md` §3.5.
|
||
|
||
1. **Character Encoding Safety**: Never use Japanese kana (の, が, は), rare symbols, or Private Use Area characters in content strings. They corrupt to U+FFFD (<28>) during LLM→file write→read transit. Replace with plain Chinese equivalents: `の`→`之/的/缔/省略`.
|
||
2. **Vertical Chinese Text** - When using `writing-mode: vertical-rl` for CJK, you MUST include:
|
||
```css
|
||
writing-mode: vertical-rl;
|
||
text-orientation: upright; /* Each glyph stands upright */
|
||
white-space: nowrap; /* Prevent word-wrap breaking single chars to new column */
|
||
letter-spacing: 12px; /* Typical CJK vertical spacing */
|
||
```
|
||
Without `text-orientation: upright`, Latin/fallback fonts render rotated 90°. Without `white-space: nowrap`, CJK characters may wrap into unexpected multi-column layouts (e.g., 3 chars on one line + 1 char alone on next).
|
||
3. **Font Coverage**: For CJK content via Playwright, always load Google Fonts Noto Serif SC or Noto Sans SC via `<link>` tag in `<head>` (NOT `@import` in CSS - `@import` must be the very first rule in a stylesheet or it's silently ignored). Example:
|
||
```html
|
||
<link href="https://fonts.googleapis.com/css2?family=Noto+Sans+SC:wght@300;400;500;700;900&display=swap" rel="stylesheet">
|
||
```
|
||
System CJK fonts vary across macOS/Linux - Google Fonts guarantee glyph coverage without relying on system fonts. `design_engine.py` already handles this automatically via `<link>` tag.
|
||
4. **Post-Generation Text Verification**: After Playwright renders the PDF, extract text from every page and scan for `?` or `\ufffd`. If found, the source HTML has encoding-corrupted characters that must be replaced in the Python source.
|
||
5. **🚨 HTML Pre-Render Validation (MANDATORY)**: After writing the HTML file and before running `html2pdf-next.js`, always run the HTML validator:
|
||
```bash
|
||
python3 "$PDF_SKILL_DIR/scripts/poster_validate.py" check-html <your_file>.html
|
||
```
|
||
- **ERROR** items (e.g. `OVERFLOW_HIDDEN_CONTAINER`, `FONT_NO_FALLBACK`) → must fix before PDF generation. Use `--fix --output <file>.html` for auto-repair.
|
||
- **WARNING** items (e.g. `FIXED_SIZE_NO_SCREEN_ADAPT`, `SCREEN_ADAPT_NO_SCALE`, `COLOR_CONTRAST`) → review and fix where appropriate.
|
||
- This catches the most common bypass HTML bugs: `overflow:hidden` on containers, missing `@media screen` auto-scale for fixed-size pages, font-family without generic fallback, low contrast text, etc. |
