Content-Transfer-Encoding: 8bit

- ✅ **`globals.css`** — Edit `.chat-pane`: remove `width: 380px`, add `min-width: 0`, `overflow: hidden`, `transition: width 0.2s ease`
- ✅ **`globals.css`** — Insert `.chat-resize-handle`, `.chat-header`, `.chat-collapse-btn` rules after `.chat-pane` block
- ✅ **`globals.css`** — Append `::-webkit-scrollbar` rules at end of file
- ✅ **`ChatPane.tsx`** — Full rewrite: new props interface, header strip, conditional body, inline width style
- ✅ **`App.tsx`** — Add `chatWidth` + `chatCollapsed` state with lazy localStorage initialisers
- ✅ **`App.tsx`** — Add two `useEffect` persistence hooks
- ✅ **`App.tsx`** — Add `handleResizeMouseDown` function
- ✅ **`App.tsx`** — Update `.main-content` JSX: insert conditional resize handle div, pass new props to `<ChatPane>`
