/* ==========================================================================
   NEXORA — Admin Dashboard Suite Stylesheet
   --------------------------------------------------------------------------
   Styles ONLY the admin/*.html pages (dashboard.html, settings.html).
   Reuses the same design tokens (CSS custom properties) defined in
   css/style.css :root — so the admin panel always matches the public
   template's dark glassmorphism + cyan/purple gradient visual identity
   even if a buyer re-themes the main site colors.

   Load order on admin pages:
     css/style.css  -> base tokens, buttons, typography, utility helpers
     css/admin.css  -> this file (admin-only layout/components)
     css/rtl.css    -> RTL overrides (admin section is already covered
                       there — see "16. Admin Dashboard & Settings")

   TABLE OF CONTENTS
     1. Admin Shell Layout (sidebar + main)
     2. Sidebar Navigation
     3. Topbar
     4. Stat Cards
     5. Panels / Cards / Section headers
     6. Settings Forms (inputs, API key fields, toggles)
     7. Tables (plan editor rows)
     8. Toast / Inline feedback
     9. Responsive
