/* ==========================================================================
   NepaEducation Design System  (public site)
   --------------------------------------------------------------------------
   Stack: Laravel Blade + Bootstrap 4.1 (loaded before this file).
   Rules:
     1. Components never use raw colours — only the semantic tokens below.
     2. New looks = new variant classes (.btn-*, .nx-card--*, .nx-icon--*),
        never inline style overrides in Blade.
     3. Spacing follows an 8px scale (--space-*).
     4. Motion uses transform/opacity only and honours prefers-reduced-motion.

   Palette — taken directly from the NepaEducation logo (logo.svg):
     #34449C royal blue   → Primary   : trust, focus, technology
     #242062 deep indigo  → Navy      : premium, calm backdrop for hero & footer
     #333366 indigo       → Foreground: wordmark colour, used for headings
     #6664AD periwinkle   → Glow      : highlights / gradients on dark
     #D32027 brand red    → Accent    : energy, urgency, calls-to-action
     (#B31F24 / #E71E25 are the red's hover/bright shades)
   Harmony: complementary (indigo 231° ↔ red 358°).
   All text/background pairs below meet WCAG AA (≥ 4.5:1 for body text).
