/* ==========================================================================
   DARK ROOM — restate.fi design system v0.1
   1 tokens · 2 base · 3 type · 4 ornament (tape) · 5 components · 6 page
   7 responsive · 8 motion

   Ported from the design canvas (reference/canvas/darkroom.css). Class names are
   unchanged (rm- prefix) so the two can be compared directly. Two differences:
   container queries became media queries, and cqi units became vw.

   Rules: no gradients, no glow, no blur shadows, no glassmorphism, no emoji.
   Radius 0 on containers; 3px / fully rounded only on bar-like elements.
