Approved design for the second sub-project of Phase 1: manual user collections (named groupings of audiobooks) and ordered playlists (queue with cover image). Both profile-scoped, with cross-user public visibility. Includes migrations 149-152, two REST surfaces sharing a uniform CRUD shape, in-memory test fakes parallel to the bookmark sub-project's harness, and the same anti-enumeration 404 security pattern.
