Usage: local-build-macos.command --output-dir DIR [options]

  --workspace DIR                 Repository root (default: this script's parent directory)
  --profile {base|retro-rewind|both}  Product to build (default: base)
  --output-dir DIR                Output .app directory (required; Retro Rewind for both)
  --base-output-dir DIR           Base .app directory (required with --profile both)
  --game IMAGE --nodtool PATH     Extract and verify a clean PAL RMCP01 disc image first
  --retro-rewind-package-dir DIR  RetroRewind6 directory (required for Retro Rewind)
  --retro-wfc-offline-dir DIR     Directory containing binary/payload.RMCPD00.bin
  --skip-retro-wfc-payload        Build Retro Rewind without the shared Retro-WFC payload
  --force-clean-build             Delete local generated and native-build-macos caches
  --parallel N                    Pin translation and build parallelism
  --cmake PATH --ninja PATH       Override build tools
  --dotnet PATH                   Override dotnet
