Agent Skills: expo-ios-screen-scaffolder

Scaffolds Expo (React Native) iOS screens that follow Apple Human Interface Guidelines by construction — list, detail, form, modal sheet, native tabs layout, and settings screens, each wired with native navigation, FlashList, safe-area insets, semantic colors, SF Symbols, haptics, and empty/loading states. Generated code follows the expo-ios-hig rules so it passes expo-ios-hig-verify without rework. Each screen is TSX for Expo Router, not Swift. Trigger whenever the user wants to create, add, generate, or scaffold a new Expo screen, route, tab layout, or form for iOS — even if they don't mention HIG.
