/* css/trip-cost-split.css -- Group cost-split widget styles.
 *
 * Self-contained block; not threaded through tailwind.config.js because the
 * widget is a vertical slice we want to be able to ship or yank without
 * touching the rest of the design system. Colors reference the muddytires
 * palette (forest / amber / basalt / paper / trail) so the widget feels
 * native when dropped into a trip view.
 *
 * Usage: <link rel="stylesheet" href="/css/trip-cost-split.css">
 * Then a container with [data-trip-cost-split-code="ABCD1234"] auto-mounts.
