/* ============================================================
   VIRIDEON — one page
   Built to Brand Guidelines interim v1.
   Two families (Inter + IBM Plex Mono). Ink and white carry the
   brand; green is punctuation. Flat, hairline, generous, left-aligned.

   TWO DOCUMENTED DEVIATIONS, both for WCAG AA, both one-line reverts:
   1. --green-ink #15803D for green TEXT on light grounds.
      The brand accent #22C55E is 2.28:1 on white — it cannot legally
      carry text. #22C55E is retained unchanged for every NON-TEXT use
      (dots, rules, fills, the dark-band accent).
   2. --slate-500 #64748B for tertiary TEXT on light grounds.
      Brand Slate 400 #94A3B8 is 2.60:1 on white. #94A3B8 is retained
      for non-text detail and for tertiary text on ink, where it passes.
