2. Backend — Go packages, domain rules, application flow, and HTTP API
3. Frontend — Svelte views, state, and transport abstraction
4. Real-time transports — HTTP + SSE and bidirectional WebSocket modes
5. Persistence — SQLite, PostgreSQL, migrations, and the stored aggregate
6. Testing and demos — automated checks and Playwright recording
