/* ============================================================
   UVEOUS ERP — THEME  (theme.css)
   ------------------------------------------------------------
   SINGLE SOURCE OF TRUTH for brand tokens + global styles.
   Brand: Uveous Softtech Pvt. Ltd. (logo palette)

   • Light theme is the DEFAULT.
   • Optional opt-in dark mode:  <html data-theme="dark">
   • Every colour/shape is a CSS variable — change it here once
     and the whole portal updates.
   ------------------------------------------------------------
   Load this file BEFORE the local stylesheets (design-system,
   nav, home, site, admin) so they can consume the tokens.
