===============================================================================

CSS ARCHITECTURE RULES:
- This file contains COMMON rules used by both mobile AND desktop
- Mobile-specific rules are in mobile.css (max-width: 1339px)
- Desktop-specific rules are in desktop.css (min-width: 1340px)
- Rule migration logic:
  * If common rule exists + mobile rule exists + desktop rule missing → Copy common to desktop, remove from common
  * If common rule exists + desktop rule exists + mobile rule missing → Copy common to mobile, remove from common  
  * If common rule exists + both mobile and desktop rules exist → Remove from common
  * If common rule exists + neither mobile nor desktop rules exist → Keep in common
- Mobile and desktop rules never overlap due to media queries, avoiding inheritance issues

PROPERTY-LEVEL MIGRATION:
- When moving rules from common to mobile/desktop, verify ALL CSS properties are accounted for
- Compare each property: common vs mobile vs desktop
- Copy missing properties from common to target file(s)
- Only remove common rule after all properties are properly migrated
- If conflicting values exist, keep the specific (mobile/desktop) value
- Merge properties into existing rules, don't create duplicate rules
