/* ==========================================================================
   Ozituma dashboards — token proposal
   Lift this file directly into apps/web/app/globals.css.

   Rules honoured here:
   - Colours in oklch().
   - The six admin-overridable properties (--ink, --paper, --accent,
     --header-bg, --footer-bg, --link) and --wrap are DECLARED but never
     relied upon literally anywhere else: every dashboard colour is derived
     from them with color-mix(), so a re-themed palette carries through.
   - No fixed page width is assumed; --wrap governs measure.
