 `/404`. The build writes static assets to `dist/client/` and the SSR runtime to
 `dist/server/`; deploy `dist/client/` for a static host.
 
+## Deploy
+
+The output in `dist/client/` is plain static files, so any static host works.
+Everywhere, the **build command** is `pnpm build` and the **publish directory**
+is `dist/client`. Set `VITE_SITE_URL` to your origin (see [SEO](#seo)).
+
+### Vercel
+
+Use the button at the top (or import the repo). Config lives in `vercel.json`
+(`outputDirectory: dist/client`, `framework: null`).
+
+### Cloudflare Workers
+
+Use the button at the top. Config lives in `wrangler.jsonc` as an assets-only
+Worker (no server code) serving `dist/client`, with
+`not_found_handling: "404-page"` for the prerendered `404.html`. Cloudflare runs
+`pnpm build`, then `wrangler deploy`.

+### Cloudflare Pages
+
+No one-click button — Cloudflare's deploy button is Workers-only. In the
+dashboard, **Create → Pages → Connect to Git**, then set **Build command**
+`pnpm build` and **Build output directory** `dist/client` (Framework preset:
+none). Pages serves `404.html` automatically. `wrangler.jsonc` is not used by
+Pages.
