   MAZECUT — styles.css

   Visual direction:
   - Dark photographic studio
   - Warm orange / cream accents
   - Large editorial typography
   - Strong contrast
   - Separate mobile layout instead of a squeezed desktop view

   This file is intentionally expanded and commented so it is
   easier to edit in VS Code.
