   MEDISPA.PRO DESIGN TOKENS & BASE STYLES
   Version: 1.1 (Bank-Grade Brand Aesthetic, WCAG 2.1 AA)
   Pure CSS Tokens for Light & Dark Themes

   2026-10-26 (owner decision): contrast brought to WCAG 2.1 AA (normal text >= 4.5:1, large text and UI >= 3:1).
   The old values FAILED AA and must not come back for text or for white-on-green fills:
     white on #21A038 -> #00B140 gradient   3.41 / 2.85  ->  white on #008837 -> #1B872F   4.59 / 4.61
     green text #21A038 on white / #F7F8F9  3.41 / 3.21  ->  --brand-green-ink #007A32     5.48 / 5.16
     muted text #94A3B8 on white / #F7F8F9  2.56 / 2.41  ->  --text-muted #5F6C80         5.33 / 5.01
     dark: muted #64748B on #141A22         3.68         ->  #94A3B8                      6.82
   #21A038 / #00B140 stay for decoration only: borders, dots, icons, chart lines, glow, the 20px+ bold ".PRO".
