/* ============================================
   LOGIN ICON STYLES - PERMANENT SOLUTION

   CRITICAL: These styles are in custom.css instead of Tailwind utilities
   to solve the circular CSS dependency problem.
   
   THE PROBLEM:
   - Tailwind utilities (w-16, h-16, bg-gradient-to-br) were missing from compiled app.css
   - Rebuilding CSS to include them broke Bootstrap navigation menus
   - Created unusable circular dependency: icons work OR navigation works, not both
   
   THE SOLUTION:
   - Move all custom UI elements to custom.css (loads after Tailwind)
   - Use !important declarations to override any framework conflicts
   - Navigation menus stay intact regardless of CSS rebuilds
   - Custom components work independently of Tailwind build process
   
   DO NOT move these back to Tailwind classes or inline styles!
   See docs/css-architecture-fix.md for full technical details.
