   COSMIC CATS - CLEANED & OPTIMIZED STYLESHEET
   🎯 PURPOSE: A clean, deduplicated, and functional stylesheet for the entire site.
   📄 USED BY: index.html + all *-content.html files
   ✨ FEATURES: Neon semi-transparent look, responsive design, all features preserved.
   
   ⚠️ REMINDER: When adding new code, merge with existing sections! 
   ⚠️ Put main-content styles with other main-content styles!
   ⚠️ Avoid code bloat - organize by functional sections!
