Add a database-style object-store abstraction: the objstore lookup resolves the active engine (seaweedfs|minio) per consumer and yields a uniform S3 payload, objstore_secret_key is auto-generated like database_password, sys-svc-objstore delegates per-consumer provisioning to the resolved provider's objstore_init entrypoint (lazy-loading the provider when it was not preloaded), and compose/network/volume plumbing supports both a shared central instance and an embedded storage-only instance per consumer. Add the web-app-seaweedfs provider role: Filer and Master UIs behind the admin-only oauth2-proxy via a role-local nginx and proxy.conf.j2 (S3 API domain stays ungated, admin UIs deny with 403 when SSO is disabled), per-consumer S3 identities from s3.json, idempotent bucket provisioning via weed shell, a /24 on the central-provider subnet range, Playwright coverage for admin/biber/guest plus consumer bucket existence, and unit tests for the objstore lookup and the per-engine compose volumes. Mark web-app-minio lifecycle: unsupported, move its mc client image into a dedicated services.client entry, align it with the objstore credential contract, and make its consumer provisioning idempotent.
