/*
  House of Mastery — Shared Design System
  hom.css v1.0
  ─────────────────────────────────────────────────────────────────────────────
  Single source of truth for:
    1. Design tokens (colors, spacing, radius, shadow, font)
    2. Typography scale — 5 levels, mobile-first, one desktop override block
    3. Base element resets
    4. Shared layout utilities
    5. Navigation (shared across all pages)
    6. Footer (shared across all pages)
    7. Button system
    8. Responsive protocol:
         Mobile  : base styles (no @media wrapper)
         Desktop : single @media (min-width: 768px) block
         Wide    : single @media (min-width: 1100px) block
  ─────────────────────────────────────────────────────────────────────────────
  DO NOT use !important anywhere in this file.
  Page-specific overrides live in each page's own <style> block.
