/* Health Defender — Design Tokens (DARK v3)
   Import into any page:  <link rel="stylesheet" href="tokens.css">

   DARK THEME NOTES
   --------------------------------------------------------------
   - Semantic token names (--paper, --ink, --surface, etc.) are retained so
     existing section CSS continues to work. Only the *values* changed.
   - Two dark surface levels:
       --paper      = page base (deepest)
       --paper-alt  = alternating section (very subtle lift)
       --paper-tint = proof / card sections (clearest clinical elevation)
   - Text opacities follow the dark-UI playbook:
       primary  90-95% white
       soft     72%
       muted    48%
   - Lime (#97F500) is the single accent and earns its keep on dark —
     used on CTAs (dark text on lime), eyebrows, hairlines, glows.
   - Navy tokens are preserved for occasional blue moments (icons, medical
     cues) but never used as section backgrounds now; the page IS darker
     than navy.
