/* ==========================================================================
   REDESIGN GUIDE FOR CLAUDE CODE
   ===========================================================================
   To completely redesign this site, edit ONLY these locations:

   1. COLORS: Change the CSS variables below in :root
      - --primary, --primary-dark, --primary-light, --primary-rgb
      - --secondary, --secondary-dark, --secondary-light, --secondary-dark-rgb, --secondary-rgb
      - --accent, --accent-dark, --accent-light, --accent-rgb
      - --text-primary, --text-secondary, --text-muted
      RGB channels MUST match their hex counterpart (e.g. #e63946 = 230, 57, 70)

   2. FONTS: Change TWO places:
      - --font-primary and --font-heading below
      - AUTO365_GOOGLE_FONTS_URL constant in functions.php (top of file)

   3. SPACING/RADIUS: Change --space-* and --radius-* variables below

   4. SHADOWS: Change --shadow-* variables below

   DO NOT touch: EU label colors, season colors, stock status colors
   (these are product-attribute semantic colors, not brand colors)
