/* Sandwich Open Mic collection (comunidad) - layout and motion, from
   David's 2026-10-03 prototype. Load after /shared/tokens.css, which
   supplies the reset, font stack, link and focus styles. The colour
   palette (:root --background/--text/--muted/--accent/--line, light and
   dark) lives in the page's own <style> block, per tokens.css's
   convention, so the contrast check can verify it. */
