/* ============================================================
   momentum.css — the shared design system for the "Momentum"
   site (static/). Every page loads this first and
   layers page-specific styles on top.

   The three comeback stages ARE the brand: each owns a color,
   and the signature gradient runs through them in stage order —
   brewing (cyan) → gaining (amber) → verge (rose). Gold is
   reserved for winners and "prime setup" games (home + primetime),
   so it always signals "this is the special thing on the page".
