/* ============================================================================
   JFDA E-Services Register — Arabic-first (RTL) styling on top of MudBlazor.

   MudBlazor supplies the component layer and the theme tokens (see JfdaTheme.cs);
   this file adds the app's own surface treatment, the status ramp helpers, and
   markdown/typography rules MudBlazor doesn't cover.

   Status colours come from StatusPalette and were validated for colourblind
   separation and contrast against each mode's own surface, not eyeballed.
