Railway, DigitalOcean and `docker build` use a root Dockerfile with no setting, and it is
Coolify's and Dokploy's default path. The file moves; nothing is copied.
- VOLUME /data is gone. Railway rejects the line, and a named volume is needed anyway
(VOLUME alone gives each new container a fresh anonymous one). The platforms mount /data.
- The baked PocketBase gate's comment named the old path. It now says the repo-root
Dockerfile, and the gate's SHA-256 pin moves with it (2987055b... -> 2eceef03...). The
hook's code is unchanged: the exact RUN passes `sha256sum -c`, and the old block still
passes its old pin.
- .dockerignore excludes everything: the Dockerfile copies nothing from the build context,
so no platform sends the whole repository to the builder.
- compose.yaml: the same image with its /data volume and memory limit; settings from .env.
- deployment/cloud/README.md gains "Where it runs": Coolify, Dokploy, Railway, a server with
Docker, Kubernetes, and why not DigitalOcean App Platform (no persistent volumes).
DEPLOY.md and two comments follow the move.
