   Terra Vita Hub v444 — Site-wide UI coherence lock
   Purpose: one visible institutional product language across public,
   protected and reviewer surfaces. This layer only normalises presentation:
   spacing, cards, buttons, containers, typography rhythm and search cards.
   It does not change routing, auth, Supabase, SQL, protected data access,
   review logic, readiness posture or institutional authority boundaries.
