 ## Rebrand the deployment
 
 Edit the root `branding.json` to set the product name, domain, logo path, public copy, contact addresses, documentation and source links, and footer credit.

Keep `.env` API and WebSocket overrides for deployments whose service endpoints differ from the public brand domain.

+`.gitea/workflows/docker.yml` builds the Docker image when `main` is updated and can also be started manually from the Actions page. It publishes `git.anchorhost.eu/anchorhost.eu/anchorhost-frontend:main-latest` and a commit-specific `main-<12 character SHA>` tag to the Gitea Container Registry. The workflow uses Gitea's job token with only `contents: read` and `packages: write`; no registry password secret is needed.

+Enable Actions and the Container Registry for the repository, and register an `ubuntu-latest` runner that has the Docker CLI and access to a working Docker daemon. The workflow cannot build until that runner is available. `.dockerignore` keeps local dependencies, Git history, build output, and recovered production artifacts out of the build context.
