/* ==========================================================================
   matchwire design system
   --------------------------------------------------------------------------
   Aesthetic: flat poster. Warm amber field, white cards, heavy black type.
   Two colours only: amber and ink, plus warm off-whites for insets.
   Native CSS, no build step, no framework, no webfont link.

   Honest notes:
   - system font stack (SF Pro on Apple hardware), heavy weights for display
   - links are ink with an underline; there is no second hue that passes
     contrast on both amber and white, so nothing tries to be a link colour
   - single theme, on purpose. The amber field is the brand, so the page does
     not invert with the OS. color-scheme is locked to light. Text that needs
     contrast sits on a white surface.
   - the live board is plain text and real grid cells on purpose: a reader
     (human or model) gets the same information from the HTML that the design
     shows visually. Nothing meaningful is CSS-only. Every cell carries
     data-mw-* hooks so a feed can fill values without touching the markup.

   Shape rule (documented, one system):
     surfaces 24px, chips 8px, controls pill.
