-## 🧪 Scripts
 
 ```bash
-bun dev        # Run development server
+npm install
-bun run build  # Build for production
+npm run dev
-bun start      # Start production server
+```
 
-bun test       # Run tests (if configured)
+Open [http://localhost:3000](http://localhost:3000) — redirects to `/et` by default.
-bun run lint   # Run linter (if configured)
+
+---
+
+## Scripts
+
+```bash
+npm run dev        # Dev server (Turbopack, localhost:3000)
+npm run build      # Production build (outputs SSG for /et and /en)
+npm start          # Serve production build
+npm run lint:fix   # ESLint with auto-fix
+```
+

+  original/            # Original PNG sources (not served)
+scripts/               # Image processing utilities
+```
+
+---
+
+## Image Utilities
+
+When adding or replacing images, re-run:
+
+```bash
+# Convert new PNGs → WebP (quality 85)
+node scripts/convert-images.mjs
+
+# Regenerate blur placeholders for all images
+node scripts/gen-blur-placeholders.mjs
+```
+
+---
+
+## Localisation
+
+Translation files live in `translations/et.json` and `translations/en.json`.  
+Routing is handled by `src/proxy.ts` — `/` redirects to `/et` (default locale).
