   DiffLab Brand Site — shared stylesheet
   branding.difflab.ai

   Load order (every page):
     1. /tokens/tokens.css   (all --dl-* custom properties)
     2. /css/site.css        (this file)

   RULES
   - No raw hex/hsl color values in this file. Colors only via var(--dl-*),
     color-mix() over those vars, `transparent`, or `currentColor`.
   - Dark-first brand surface; both themes fully supported via the semantic
     tokens (--dl-bg, --dl-fg, --dl-surface, --dl-accent, ...).
