React 19 TanStack Start frontend (`web/app/src/routes/__root.tsx`, `index.tsx`, `routes/api/*`). Talks HTTP (NDJSON + SSE) only — never imports `@earendil-works/*` directly. Renders agent turns (`AgentSessionEvent`) as cards (tool calls, plans, questions). Session sidebar, attachments, multi-project registry. Routes handle `post-chat`, `attach`, and stream endpoints.
