   Design tokens first, then layout, then components. Tailwind utilities handle
   spacing/interaction ergonomics; this sheet owns the theme tokens, the iOS-
   style slider switches, and the pieces Tailwind cannot express cleanly.

   Performance note: everything here is static CSS. There are no runtime
   style recalculations, no layout thrash and no web fonts, which keeps the
   first paint fast on low-end mobile devices.
