   Paddle Stack — design system

   Tokens are role-named, never hue-named, so light and dark resolve as
   complete sets. Nothing declares a colour outside :root / the theme
   blocks below.

   Palette is grounded in an outdoor court: cool paper surround, deep
   court blue, kitchen teal, and optic lime kept exclusively for the
   "live right now" state so it never becomes decoration.
