Run the original macOS ARM64 game code on iOS: - tools/retarget.py: header-only Mach-O retargeting to an iOS dylib - platform/native: UIKit host and macOS API shims (AppKit for SDL's Cocoa backend, CoreGraphics displays, CoreAudio device, Metal device properties, Wuffs PNG decoding, Steam and peripheral stubs) - touch, overlay, iOS keyboard and hardware keyboard input - tools/build_native.py: build, sign, install, data copy, launch - docs: build guide, controls, architecture Also includes the earlier static-translation research (ARM64 -> WASM -> native) under docs/research, runtime/, tests/ and tools/. No game files are included; the build reads them from a local install.
