Tailwind Config Changes Not Reflecting in Dev

1. Dev server not watching tailwind.config.js
2. PostCSS not recompiling after config change
3. Vite build cache needs clearing
4. Content path changes not triggering rebuild
5. IDE not saving file or watching disabled

Ensure vite.config.js watches config file:

export default {
  server: {
    watch: {
      include: ['./tailwind.config.js']
    }
  }
}

Clear cache and restart: `rm -rf node_modules/.vite && npm run dev`

Or manually hard refresh browser (Shift+F5).
