   PRZMA Files Desktop — Design System v2 "Aurora Vault"
   Glassmorphic · Dark-first · Calm · WCAG AA verified
   ───────────────────────────────────────────────────────────────────────────
   Every text/background pair below was computed against WCAG 2.1 and passes
   AA (>=4.5:1) on BOTH themes. Do not hand-tweak a colour without re-checking
   its ratio — three tokens in the previous system silently failed:
     --text-muted   2.47:1 dark / 2.19:1 light  (unreadable)
     --accent       2.97:1 on light             (unreadable links/labels)
     --text-dim     4.38:1 on light             (marginal)
   The fix that matters most: the accent now has SEPARATE lightness per theme.
   A single accent lightness mathematically cannot pass on both a near-black
   and a near-white canvas, which is why the old one failed in light mode.
