   VELVET ROOM - UNIVERSAL BLACK CARD AUTHORITY U4B
   2026-08-24

   CANONICAL DOCTRINE
   - Post cards are universally black.
   - Post origin/distribution mode remains metadata and behavior.
   - Social/Friends/Work mode artwork belongs to the surrounding Room surface.
   - Media, reactions, comments, menus, identity, and navigation are untouched.
