   Developer site — design system.
   Implements the token contract from the "Developer Site Template"
   design canvas (artboard 01).

   One accent value drives buttons, icon tiles, figures, chart lines
   and emphasis. Everything else is fixed across all apps and pages.

   Contrast rules baked in:
     --brand      #FF5500  fills, figures >= 40px, graphics ONLY
     --brand-text #C93F00  every accent that is TYPE (5.0:1 on cream)
     --ink-3      #A89E97  2.4:1 — decorative only, NEVER type
