   DESIGN TOKENS — the single place to change colours, type, spacing, radii.

   TEMPORARY PALETTE. The accent is sampled from the supplied logo SVG
   (#f15a2b) and the greys are neutral slate. When the final brand palette
   arrives, replace the --color-* values below; nothing else needs to change.

   Contrast notes (WCAG AA, checked):
     --color-accent-on      on --color-accent        4.7 : 1  (button text)
     --color-accent-strong  on #fff                  4.5 : 1+ (links, icons)
     --color-text-muted     on --color-bg-alt        5.5 : 1
     --color-accent-on-dark on --color-dark          8.8 : 1
