/* ————————————————————————————————————————————————————————————————
   Localish design system — macOS-native by derivation, not imitation.
   · Appearance: color-scheme tracks the system; every color is a CSS
     system color (Canvas, CanvasText, AccentColor…) or derived from one
     with color-mix, so dark mode and the user's accent come for free.
   · Type: the system font uses a 106.25% root size (17px at the default
     browser setting); the ramp is rem-relative.
   · Structure: cascade layers (tokens → base → components → utilities),
     native nesting, light-dark(), container queries.
