   VoltraPay — Design Token Layer
   ----------------------------------------------------------------------------
   Single source of truth for the VoltraPay brand. Loaded LAST in index.html
   so its :root / [data-theme="dark"] blocks override the legacy admin
   template tokens (public/assets/css/style.css) by cascade source-order.

   - Redefines the legacy token names the template already consumes
     (--primary-*, --neutral-*, --brand, --lilac-*) so existing screens
     re-skin automatically.
   - Adds new brand tokens (--vp-*) consumed by src/components/ui/* primitives
     and Tailwind (via tailwind.config.js var() mappings).

     Convention: the 50/100 steps are TINTED FILLS (chips, alerts, soft
     buttons) and the 700 step is the TEXT/ICON colour that sits on them, so
     both must flip for dark mode — otherwise a "bg-success-50" chip stays
     near-white and burns a hole in a dark screen. The 500/600 steps stay
     saturated: they are solid action fills that carry white text in both
     themes. */
