# Add any new package types to both PACKAGE_DEFINITIONS and the PackageDef union.
# Europractice quad packages use the QuadPackageDef pin numbering (CCW from
# top-left) which matches EP's GDS labels. EP-specific cell names, layer
# conventions and pin_map strings live in chipflow-backend's packaging_klayout
# plugin (data/ep_packages.json), keeping this library vendor-agnostic.
