/* ============================================================
   GRAMMAR KINGDOM — DESIGN SYSTEM
   Principles adapted from DESIGN.md: one 8px spacing rhythm,
   a single radius scale with pill accents, weight-driven type
   hierarchy, plum-tinted shadows used sparingly, and a pastel
   "world block" palette where color — not shadow — sets the
   scene. Identity stays Grammar Kingdom: warm parchment canvas,
   royal plum ink, adventure green primary, chunky toy buttons.
