# SortIQ macOS build — arm64 native (Apple Silicon)
#
# Produces:  SortIQ-1.3-macOS.dmg
# Runs on:   Apple Silicon natively; Intel Macs via Rosetta 2 (automatic)
#
# Note: universal2 (fat arm64+x86_64) is not used because pydantic_core and
# several other pip wheels only ship single-arch arm64 binaries.
# Rosetta 2 on Intel Macs handles arm64 apps transparently at near-native speed.
#
# Requirements:
#   brew install create-dmg  (for the .dmg step)
#   pip install pyinstaller pillow
