      Custom Components
      (code, links, etc.)

Markdown Components

Element	Custom Handling
code	Inline vs block detection, syntax highlighting label, copy button
a	External link (new tab), primary color styling
pre	Background styling, overflow scroll
Lists	Proper indentation and spacing
Tables	Border collapse, header background
Blockquotes	Left border, muted color

Typing Indicator Animation

@keyframes bounce {
  0%, 60%, 100% { transform: translateY(0); }
  30% { transform: translateY(-4px); }
}

/* Staggered delay for dots */
.dot-1 { animation-delay: 0ms; }
.dot-2 { animation-delay: 150ms; }
.dot-3 { animation-delay: 300ms; }

Input Handling

Key Combinations:

• Enter - Send message
• Shift+Enter - New line
• Auto-resize up to 200px max height

State Management:

• Textarea value tracked in local state
• Height recalculated on content change
• Focus maintained after send

Gateway Integration

Connection Awareness:

• Warning banner when Gateway offline
• Input disabled without connection
• Fetch history only when connected
• Error display for failed messages

Welcome Screen Features

Quick start cards showing:

• "Ask Questions" - General Q&A capability
• "Creative Tasks" - Writing and brainstorming

Gradient branding with ClawX logo.

UI/UX Considerations

1. Message Alignment: User messages right-aligned, AI left-aligned
2. Avatar Design: Gradient for AI, solid for user
3. Hover Actions: Progressive disclosure of copy buttons
4. Feedback: Toast on code copy, visual state for copied
5. Loading States: Typing indicator during AI response
6. Error Handling: Inline error display with icon
