  ⚠️ ARCHITECTURE NOTE (v3, May 2026)
  ──────────────────────────────────────────────────────────────────
  Core design tokens (--accent*, --ink*, --bg*, --line*, --radius-*,
  --text-*, --space-*, type stacks, --hover*, --transition*) live in
  the :root block BELOW and in the design-system reference
  (colors_and_type.css). ONE declaration each — do NOT redeclare any
  of these tokens in other files.

  If you're about to write `--radius-md: 12px` somewhere else, STOP.
  That value is wrong (v2 is 8px) and duplicating it creates cascade
  drift. Use var(--radius-md) and let this file own the value.
