Supabase Row-Level Security (RLS)
Postgres-level access control that gates every row in ShelfSEO's database by the authenticated user_id — defense in depth even if the app layer leaks.
Every user-scoped table has policies like 'select_own' that filter by user_id = auth.uid(). Agency mode uses is_agency_member(agency_id) for cross-account access.
