   drjenchen-mockup — design tokens & styles
   Fluid type: D:\ClaudeCode\fluid-fonts\production variables.txt
   (CCAH clamp scale, verbatim). Body floors raised per
   docs/UI-UX-STANDARDS.md (body >=18px, nothing under 16px,
   2026-07-28) — so body copy uses the body-big token and the
   0.875rem body-small token is deliberately absent.
   Spacing: Fluid Space Forge scale (375->1920px viewport),
   verbatim, plus one project token (--sp-section).
   Palette validated 4.5:1 / 3:1 across every surface pair,
   hover states included — see docs/contrast-matrix.md.
