# run-macos.ps1 — Cross-compile WoWee for macOS (arm64 or x86_64) inside a Docker container.
#
# Usage (run from project root):
#   .\container\run-macos.ps1 [-RebuildImage] [-Arch arm64|x86_64]
#
# The macOS SDK is fetched automatically inside the Docker build from Apple's
# public software update catalog.  No manual SDK download required.
#
# Environment variables:
#   WOWEE_FFX_SDK_REPO  — FidelityFX SDK git repo URL (passed through to container)
#   WOWEE_FFX_SDK_REF   — FidelityFX SDK git ref / tag      (passed through to container)
