/* Portfolio design tokens
   Source of truth: Figma library "Portfolio Design System" (Fc2W4AI2RqF8boFIx17oQm).
   Naming: Figma variable color/bg/page = CSS --color-bg-page.
   Values come from the Phase 2 audit (2026-10-28). Reference: design-system/tokens.md
   Change Figma first, refresh test/figma-variables.json, then change the value here.
   test/figma-tokens-check.js (run by the commit hook and ship.sh) fails when the two disagree. */
