Delete declarations that Periphery reports unused on every platform that compiles them (iOS, macOS, tvOS), including nine views used only by their own previews. Platform-gated code still used on another platform, device- only MPV render paths, migration models, CloudKit record names, App Intents metadata and unused parameters are kept.
