Subject: [PATCH] refactor: unify CSS color variables across public and admin

- Add new standardized color variables in variables.css:
  - Public/light theme: --bg-primary, --bg-secondary, etc.
  - Admin/dark theme: --admin-bg, --admin-bg-alt, --admin-text, etc.
  - Gradient colors: --gradient-start (#3C856C), --gradient-2 (#60ECB4), --gradient-3 (#E390FF), --gradient-4 (#9557B5)
  - Shared: --success, --error, --warning, --accent-primary, --accent-secondary
- Update all CSS files to use new variables
- Keep admin-specific variables for dark theme sections
