+# Fluid Sidebar Activity Plan
+
+## Goal
+Transform the "laggy" sidebar counters into a fluid, high-energy "Dashboard" with smooth animations and speed metrics.
+
+## Proposed Changes
+
+### 1. New Helper: `SmoothCounter` (`bin/opencode-ink.mjs`)
+- **Prop**: `value` (Target number)
+- **Logic**: 
+  - On `value` change, start a 50ms interval.
+  - Increment `displayValue` towards `value` by a dynamic step `(delta / 2)`.
+  - Effect: Numbers "roll" up rapidly instead of jumping.
+
+### 2. New Hook: `useTrafficRate` (`bin/opencode-ink.mjs`)
+- **Input**: `value` (increasing number)
+- **Logic**:
+  - Store `(timestamp, value)` tuples for last 2 seconds.
+  - Calculate delta over time -> `chars/sec`.
+  - Return `rate`.
+
+### 3. Update `Sidebar` Component
+- **Header**: `⚡ ACTIVITY (LIVE)` with blinking dot?
+- **Stats**:
+  - `📝 Chars`: Use `<SmoothCounter />`
+  - `🚀 Speed`: `<SmoothCounter value={rate} /> ch/s`
+- **Visuals**:
+  - "Pulse Bar": `[▓▓▓░░]` length depends on `rate` (higher speed = longer bar).
+
+## Verification
+1.  **Run Chat**: Ask "Write a long story".
+2.  **Observe**:
+    -   Do numbers "roll" smoothly?
+    -   Does Speed indicator fluctuate?
+    -   Is the UI responsive (no lag)?
