/* ==========================================================================
   Apexis platform — shared design system  (shared/theme.css)
   --------------------------------------------------------------------------
   ONE STRUCTURE, MANY COLOURS.
   - Everything here is FIXED across every app: layout, components, type, neutrals.
   - The ONLY thing an app overrides is the --accent-* palette, in its own app.css:

         :root { --accent-dark:#1e1b4b; --accent-mid:#3730a3; --accent:#4f46e5; --accent-light:#6366f1; }

   Extracted and generalised from the original course-price-manager.html (whose
   brand green is the default accent below).
