## 2024-05-15 - [Iconify Bundle Size Optimization]
**Learning:** The application is statically importing all icon sets into `IconifyIcon.tsx` which can cause significant bundle bloat for the Next.js client. By using just string icons with `@iconify/react`, it dynamically fetches them when needed, preventing all unused icons from being included in the JS bundle.
**Action:** Remove all static imports of `@iconify-json/*` packages in `IconifyIcon.tsx` and just pass the string to the Icon component for dynamic fetching. This avoids huge amounts of unused JSON data in the bundle.
