/* ═══════════════════════════════════════════════════════════════════════════
   mememoon.fun — shared design system  ·  THE BUOY
   One source of truth for the landing, login, checkout and dashboard. Same
   palette, type and severity language as site/index.html (kept in sync by hand;
   the landing keeps its own inline copy so it renders with zero requests).

   Severity is the ONLY thing that carries colour. Type is carried by an
   uppercase label + a coloured dot — no emoji, no rockets, no green candles.
   Empty and blind states are honest here, never filled with synthetic content.
