   MYFOOTBOL.INFO - DARK MODE UX ENHANCEMENTS
   Laravel-Inspired Premium Design System

   Implementation Strategy:
   1. Add this CSS after existing Tailwind/custom styles
   2. Add data-theme toggle functionality with JavaScript
   3. All transitions are hardware-accelerated (transform, opacity)
   4. Color palette uses HSL for smooth theme transitions
