+# kigicli.dev
+
+The Kigi landing site and the Worker that fronts it, deployed to Cloudflare as
+the `kigi-frontend` Worker on `kigicli.dev` and `www.kigicli.dev`.
+
+## Layout
+
+| Path            | What it is                                                        |
+| --------------- | ----------------------------------------------------------------- |
+| `worker/index.ts` | Worker entry point: installer proxy, `/health`, asset fallthrough |
+| `wrangler.jsonc`  | Deployment config (custom domains, assets binding, SPA fallback)  |
+| `dist/`           | The built site served by the assets binding                       |
+
+> **`dist/` is build output, not source.** It was recovered by mirroring the
+> live `kigicli.dev` deployment — the original Vite/React project that produced
+> these bundles is not in this repo. Content and copy changes therefore have to
+> be made against the hashed `dist/assets/index-*.js` and `index-*.css` files
+> directly. If the upstream source ever turns up, drop it in beside `dist/` and
+> switch `wrangler.jsonc` to point at its build directory.
+
+## Routes
+
+Assets are matched first and served directly. Requests with no matching file
+fall through to the Worker, which owns:
+
+- `GET /install.sh` — proxies `install.sh` from the Kigi repo on Gitea
+- `GET /install.ps1` — proxies `install.ps1` from the Kigi repo on Gitea
+- `GET /health` — plain-text liveness check
+- everything else — `env.ASSETS.fetch()`, which serves `index.html` for unknown
+  paths (single-page-application fallback)
+
+The installer routes are proxied rather than linked so the published install
+command (`curl -fsSL https://kigicli.dev/install.sh | bash`) stays stable no
+matter where the repo is hosted. Responses are cached for 10 minutes at the
+edge, so a push to `main` takes up to that long to show up.
+
+Because assets win over the Worker, never add `install.sh` or `install.ps1` to
+`dist/` — they would shadow the proxy routes.
+
+## Deploy
+
+```sh
+npm install
+npx wrangler deploy
+```
+
+Cloudflare Web Analytics injects its beacon `<script>` at the edge; that is why
+`dist/index.html` does not contain one and must not have one added.
