UI Code Rules

UI must NEVER own or directly modify game state — display only, use commands/events to request changes
All UI text must go through the localization system — no hardcoded user-facing strings
Support both keyboard/mouse AND gamepad input for all interactive elements
All animations must be skippable and respect user motion/accessibility preferences
UI sounds trigger through the audio event system, not directly
UI must never block the game thread
Scalable text and colorblind modes are mandatory, not optional
Test all screens at minimum and maximum supported resolutions
