- Rename React components/pages/utilities that contain JSX to `.jsx` across `web/src`
- Update import paths and re-exports to match new `.jsx` extensions
- Fix Vite entry by switching `web/index.html` from `/src/index.js` to `/src/index.jsx`
- Verified remaining `.js` files are plain JS (hooks/helpers/constants) and do not require JSX
- No runtime behavior changes; extension and reference alignment only
Context: Resolves the Vite pre-transform error caused by the stale `/src/index.js` entry after migrating to `.jsx`.
- Add multi-dimensional animation with translateY, scale, and blur transforms
- Introduce 60% keyframe for smoother animation progression
- Extend animation duration from 0.4s to 0.6s for better visual impact
- Apply cubic-bezier(0.22, 1, 0.36, 1) easing for more natural motion
- Add will-change property to optimize rendering performance
- Improve perceived responsiveness during AI response streaming
The enhanced animation now provides a more polished and engaging user
experience when AI responses are being streamed, with text appearing
smoothly from bottom-up with subtle scaling and blur effects.
