/* ==========================================================================
   ALTMASS — DESIGN SYSTEM
   Identity: premium gaming + social platform — clean light surfaces,
   deep navy/charcoal text, a bold blue-purple gaming accent, and a
   bright gold accent reserved specifically for XP/rewards so progress
   always reads distinctly from ordinary UI actions.
   Signature motif: the hexagon (XP rings, avatar frames, badges) —
   evokes an arena/hive of competition rather than generic circular UI.
   Dark mode mirrors this with inverted surfaces (see prefers-color-scheme).
