🎨 Palette: Add accessible auto-scrolling to chat timeline - #193
Conversation
This commit adds a micro-UX improvement to the `ChatTimeline` component
by implementing a screen-reader friendly auto-scroll mechanism.
1. Binds a template ref to the scrollable container.
2. Applies `role="log"` and `aria-live="polite"` so screen readers are
aware of updates.
3. Conditionally applies `aria-busy` based on the `isSending` state.
4. Uses a Vue `watch` with `{ flush: 'post' }` to safely read `scrollHeight`
after the DOM patches and automatically scroll to the bottom.

💡 What: Added accessible auto-scrolling to the
ChatTimelinecomponent in the web UI.🎯 Why: Users in chat interfaces expect the view to automatically follow the newest messages, especially when waiting for AI responses. Additionally, screen readers need explicit ARIA hints to announce live updates smoothly.
📸 Before/After:
Before: Users had to manually scroll down to read the full output of long AI responses, and screen readers did not know the container was a live updating chat log.
After: The interface automatically pins to the bottom as new messages stream in or states change, and screen readers gracefully announce updates.
♿ Accessibility:
role="log"to semantically define the area.aria-live="polite"to gently announce incoming updates.aria-busyto theisSendingstate so screen readers know when the system is actively waiting/processing.PR created automatically by Jules for task 11453457541069200238 started by @MEKXH
