/* ============================================
   PAGE LAYOUT STANDARD
   ============================================

   RULE: Components should NOT have their own
   white backgrounds or box-shadows. The page
   wrapper handles all card styling.

   Structure:
   - .page-container-wide  → max-width 1200px, centered
   - .card-white           → white card with shadow (USE THIS)
   - Component renders     → transparent, no extra box
