## Architecture

This application uses server-side rendering (SSR) with client-side hydration:

1. **Initial load:** Every page is fully server-rendered as HTML.
2. **Hydration:** `runtime.js` attaches event handlers to the existing DOM after first paint.
3. **Cross-page navigation:** Client-side fetch with content swap, no full page reload.
4. **In-page state:** Interactive regions (islands/widgets) update via RPC, not URL changes.
5. **Server push:** Real-time updates flow through SSE for background events only.

### Endpoints
