+Publish the current working tree to the permanent Cloudflare Pages development
+surface with:
+
+```sh
+pnpm dlx wrangler@4.114.0 login # first use only
+pnpm deploy:dev
+```
+
+This builds a web-only manifest for
+<https://staging.tasknotes-app.pages.dev>, connects it to the hosted staging
+Connect service and the isolated connector on `127.0.0.1:28486`, deploys only
+the Cloudflare `staging` branch, and verifies the live application. It does not
+change the production `app.tasknotes.dev` deployment. Start the matching local
+connector from the sibling `mdbase-connect` checkout with
+`pnpm dev:desktop:staging`.
+
 To update the native projects, run `pnpm cap:sync`. Android builds require Java 21. On macOS, open the iOS project with `pnpm exec cap open ios`.
