🧹 Nitpick | 🔵 Trivial

Verify SPA fallback support for BrowserRouter.

This setup only handles misses after the client boots. A direct request or hard refresh on /xyz will still return a server 404 unless the deployed host rewrites unknown paths to index.html. Please confirm that rewrite exists, or use HashRouter if the target hosting cannot provide it.

Verify each finding against the current code and only fix it if needed.

In `@src/main.tsx` around lines 9 - 11, The app currently uses BrowserRouter in
main.tsx (wrapping <App />) which requires the hosting to rewrite unknown paths
to index.html for direct navigations; verify the deployment configuration
provides that SPA fallback (rewrite/redirect unknown routes to index.html) and
confirm in the PR, or if the host cannot supply rewrites switch to HashRouter
(imported from react-router-dom and replace BrowserRouter with HashRouter around
<App />) so hard-refreshes/direct requests work without server rewrites.
