+- **How to run:** `npm run website:build`; then from `packages/website` `PORT=34567 node server.mjs` and GET `http://127.0.0.1:34567/`
+- **Pass condition:** HTTP 200 and body contains `LexAI`; `/healthz` returns `ok`
+- **Failure signal:** `Cannot GET /`, connection refused, or 500 `dist/ missing`
+- **Cost:** fast

-- **Outcome:** `packages/website` now uses the four-page structure: Home, Docs, Contribute, Community.
-- **Home:** hero + features + Getting started (Chrome / VS Code / CLI) + privacy.
-- **Routes:** `/` `/docs` `/contribute` `/community` (HashRouter).
-- **Verified:** `website:typecheck` + `website:build` passed.
-- **Next smallest action:** Deploy `packages/website` on Coolify (base `/packages/website`, static, publish `/dist`).
+- **Outcome:** Coolify `Cannot GET /` fixed — website now has a production static server and a Dockerfile.
+- **Cause:** Nixpacks built Vite `dist/` but had no `start` command; README also told Coolify to publish `/dist` (absolute empty path).
+- **Shipped:** `packages/website/server.mjs` (`npm start` on `0.0.0.0:$PORT`); `Dockerfile` + `nginx.conf`; `nixpacks.toml` `[start]`; Vite `base` is `/`.
+- **Verified:** `website:typecheck` + `website:build`; local `node server.mjs` → GET `/` 200 (LexAI HTML), `/healthz` 200, JS asset `text/javascript`.
+- **Next smallest action:** Redeploy the Coolify app with Base Directory `packages/website` (no leading slash), static site **off**, Dockerfile port 80 or Nixpacks port 3000.
