/* GDC Archive Page Styles
   Sonniss Design System — GDC Community Edition
   ============================================

   Shares the Sonniss dark foundation (#0a0a0a / #121212)
   and structural patterns (8px radius, card system, hover lifts)
   with a warm teal accent that distinguishes the community
   giveaway pages from the commercial catalogue and B2B licensing.
