+
+# Dashboard — static SPA (SvelteKit 2 / Svelte 5 / Tailwind 4 + DaisyUI 5)
+
+`npm run check` (svelte-check) is the gate — run it after editing any `.svelte` or
+`.ts` and report the result.
+
+**Static SPA (`adapter-static`) served by FastAPI from `dashboard/build` — no Node
+at runtime, no server side:**
+
+- **No `+page.server.ts`, no `$lib/server`, no form actions, no private `$env`.**
+  The dashboard only talks to `/api/*` (and `/mcp` is for external MCP clients, not
+  the dashboard). Secrets live in the backend.
+- **`npm run build` is required before FastAPI can serve `/`** — an unbuilt
+  dashboard makes the index route return a 503 with build instructions. In dev, the
+  Vite dev server (`:5173`) proxies `/api` and `/mcp` to `:8000`.
+- **The tool list is derived, not hardcoded.** `/tools` fetches `/api/tools` (which
+  the backend builds from `mcp.list_tools()`), so it stays in sync with the
+  registered MCP tools automatically. Don't hand-maintain a tool list in the
+  frontend — render whatever `/api/tools` returns, including the `premium` flag.
+- **Two routes:** `/` (status: cache/API/MCP health cards, followed teams, tools
+  list, request log) and `/tools` (interactive runner → `POST /api/run`). Shared
+  fetch/types live in `src/lib/api.ts` / `src/lib/types.ts` — update types alongside
+  backend response shape changes.
+
+**Runes & types:**
+
+- Runes mode (`$state`, `$derived`, `$props`, `$effect`); `$derived` for computed,
+  `$effect` only for genuine side effects. Props via `let { … } = $props()` (typed),
+  no `export let`.
+- `onMount` cleanup must be synchronous.
+
+**Browser telemetry:** report JS errors to `POST /api/v1/telemetry` (the
+unprotected sink) so browser failures surface in Loki at WARNING — don't let them
+be silently lost (`red_panda_standards.md`).
+
+Styling: Tailwind 4 + DaisyUI 5 components. No new CSS frameworks. No emojis in
+the UI — use an icon set.
