   IMPORTANT: This is the COLOR theme system (light/dark/auto)
   This is SEPARATE from the LAYOUT theme (.theme-clean)

   - COLOR theme: Controls backgrounds, text colors, shadows
   - LAYOUT theme (.theme-clean): Controls sidebars, layout structure

   Both systems work independently and can be combined.
