💡 What: Added `tabIndex={-1}` and `cursor-default` to full-screen backdrop overlay buttons in `MobileMenu.tsx` and `DiscussionComposer.tsx`.
🎯 Why: Backdrop buttons designed for 'click away to close' were receiving keyboard focus, creating invisible and confusing tab stops.
📸 Before/After: Visual presentation is identical, but the cursor no longer turns into a pointer over the entire screen area when the modal is open.
♿ Accessibility: Removes purely visual/structural backdrop overlays from the interactive tab order, improving the experience for keyboard-only navigation users. Documented the learning in `.jules/palette.md`.

+## 2024-05-28 - Full-screen background elements receiving focus
+**Learning:** In the app's modals and drawers (`MobileMenu.tsx`, `DiscussionComposer.tsx`), full-screen backdrop overlay elements implemented with `<button>` receive keyboard focus by default, which creates invisible and confusing tab stops for users relying on keyboard navigation.
+**Action:** When implementing clickable `<button>` elements that act purely as visual backdrops (e.g., for "click away to close"), ensure they include `tabIndex={-1}` to remove them from the tab order and `cursor-default` to indicate they are not standard interactive buttons.
