The template pointed PS_DATA_SOURCE_URI at a placeholder connection string (postgresql://user:password@host:5432/db), so the PowerSync service could never connect and crash-looped, leaving the domain returning Traefik 404s. Changes: - Add a bundled Postgres 17 service with wal_level=logical, a healthcheck, and a persistent volume; powersync waits for it to be healthy before starting. - Replace the base64-encoded config env var with a readable powersync.yaml mounted via [[config.mounts]]. Replication reads from the powersync database and bucket storage uses a separate powersync_storage database (Postgres storage requires a database distinct from the replication source). - Add an init SQL mount that creates the storage database, a demo "lists" table synced by the default sync rules, and the powersync publication required for logical replication. - Replace the unsupported sync_config block with standard sync_rules, and add an HS256 dev key so client auth works out of the box. - Remove host port mapping (Traefik routes to the container port) and point the template domain at /probes/liveness since PowerSync has no route on "/".
