/* ==========================================================================
   ADVENNO PREMIUM STRUCTURE - PHASE 3 (GLOBAL FOUNDATION SLICE)
   --------------------------------------------------------------------------
   Scope:
   - Shared shell/layout foundations only
   - Header/footer container consistency
   - Footer grid responsiveness and metadata row stability
   - No page-level redesign and no backend/business logic changes
   --------------------------------------------------------------------------
   Safety:
   - Opt-in classes only (.p3-*)
   - Minimal scoped !important only where legacy bundle already forces !important
   - No destructive overrides of legacy component behavior
