-## How it deploys
+## Deploy
 
-`npm run deploy` runs `predeploy` (build) then pushes the `out/` directory to `master` via `gh-pages`. That's what feeds the GitHub Pages backup mirror.
+```bash
+git checkout dev && git merge <branch> && git push gitea dev
+```
 
-`postbuild` drops `out/.nojekyll` so GitHub Pages doesn't ignore `_next/` assets.
+Push to `dev` triggers Gitea Actions (`.gitea/workflows/deploy.yml`):
+1. Builds the static site (`npm run build`)
+2. rsyncs `out/` to the portfolio LXC
+3. Rebuilds and restarts the Docker container serving lerkolabs.com
