+Pushes to `master` deploy to the Hetzner server via the Gitea Actions workflow
+(`.gitea/workflows/deploy.yml`), which SSHes in, pulls, builds, and restarts the
+PM2 process (`highland`, in `/var/www/highland`).
+
+Requires these **repo secrets** (Gitea → repo → Settings → Actions → Secrets):
+`SSH_HOST`, `SSH_USER`, `SSH_PORT`, `SSH_PRIVATE_KEY`.
+
+Server-side prerequisites (one-time):
+
+- A registered Gitea `act_runner` with the `ubuntu-latest` label.
+- `/var/www/highland` is a clone of this repo whose `origin` can pull the **private**
+  Gitea repo non-interactively (deploy key or token in the remote URL).
+- Node + `pm2` installed, with the app running as the `highland` process.
