/* ==========================================================================
   4BitSwap.

   One stylesheet, three parts: the design tokens, a small component library
   (bar, panel, kv, stat, chart, popover — the pieces every page here shares),
   and 4BitSwap's own components (the swap terminal, the token picker, the pool
   table).

   The shape language is a near-flat page with content on floating cards, pill
   controls and a glass header; the colour is teal on near-black, because this
   is an instrument you operate rather than a market you browse. Ink's #7132F5
   purple stays on as a second voice, for liquidity events and nothing else.

   Both themes ship. Light is the default, dark follows the OS unless the
   header's toggle has said otherwise, and every token has a value in both — so
   no rule below needs to know which one it is in.
