/* ============================================================================
   coin-terminal-ui — drop-in theme
   Extracted verbatim from apitokens.rent (Next.js + Tailwind v4), 2026-08-24.
   Values are byte-faithful to the source. Do not "improve" them.

   USAGE A — Tailwind v4 project:
     @import "tailwindcss";
     @import "./theme.css";
     ...gives you bg-bg, bg-surface, text-dim, border-line, text-positive, etc.

   USAGE B — plain CSS, no build step:
     <link rel="stylesheet" href="theme.css">
     ...the :root block + @layer components work standalone. You lose the
     Tailwind utilities, so write layout with your own CSS or inline styles.
