/* =========================================================================
   GOALFEED — design system
   =========================================================================
   Concept: a warm siren in a cold arena (branding/BRAND.md, canonical — this
   file implements it, it does not redefine it). Cold dark/ice-white ground,
   precise tabular numerals, one accent (the goal-light red) that flares only
   at the moments that matter: the primary CTA, the goal-flare in the demo,
   the score digit that just changed, and the wordmark gradient. Nowhere
   else — section headings, borders, hovers, and decorative rules use
   --ice, --muted, or --border instead. See BRAND.md's "What not to do".

   This file is a contract other pages (docs, etc.) build on. Read
   site/DESIGN.md first. Section map:

     1. Tokens (color, type, spacing, radius, shadow, layout)
     2. Reset + base elements
     3. Layout primitives (.wrap, section rhythm)
     4. Components (btn, card, code-block, tabs, callout, badge, table,
        header, footer, eyebrow)
     5. Page-specific rules (clearly marked, bottom of file)
   ========================================================================= */
