/*
   Public Background Standardization
   ---------------------------------
   Scope:
   - Public website, auth pages, checkout, and user panel only.
   - Admin panel intentionally remains independent and is not targeted here.

   Rule:
   - The layout owns the page background.
   - Page/section/hero wrappers stay transparent.
   - Cards, panels, forms, sliders, and media shells keep their own surfaces.
