/* BYKO — the design system, one stylesheet for every page.
 *
 * Token values are copied verbatim from the handoff (tokens/*.css); the
 * component rules below are the site's own recreation of the kit in plain
 * CSS, since the site has no build step and no framework.
 *
 * Rules that are easy to break and matter most:
 *   1. Blue is a legend, not decoration. --byko-live marks a value read from
 *      the chain live; a figure without blue was counted by hand.
 *   2. No opacity for text, no shadows, no radius (except controls), no
 *      animation beyond 0.15s on colour — except the market quote tape, whose
 *      motion IS its meaning; it stops under prefers-reduced-motion.
 *   3. Mono is data only — never labels, nav, kickers or field names.
