/* ==========================================================================
   BCH ECOSYSTEM RADAR — STYLES
   Architecture: CSS custom properties drive the entire palette + spacing
   scale, so re-theming is a one-block edit. Layout is CSS Grid/Flexbox only
   (no framework). Motion is centralized in the "ANIMATIONS" block at the
   bottom so timing stays consistent across the app.
