   LUXSIN X9 CONTROLLER — Global Design System
   
   Design Philosophy: Apple iOS Dark + Glass Morphism
   - Pure black background (#000000 / #0a0a0a)
   - Deep charcoal glass cards (#1c1c1e / rgba(28,28,30,0.9))
   - #00FFF6 cyan as the ONLY accent color
   - iOS-style list rows with hairline dividers
   - Frosted glass buttons with subtle inner highlight
   - Rounded corners: cards=16px, buttons=12px, toggles=full
