# Remove Qt frameworks that Blink-Qt (a Widgets + WebEngine app) does not use:
#   * QtPdf / QtPdfQuick     (+ the libqpdf image-format plugin)
#   * QtQuick3D*             (the whole 3D family)
#   * QtShaderTools
#
# A framework that is still referenced by a surviving binary is KEPT
# automatically (e.g. if QtQuick pulls QtShaderTools), unless you pass --force.
# Run this BEFORE codesigning.
#
# Usage:  ./00-slim-qt.sh            # safe: skip anything still referenced
#         ./00-slim-qt.sh --force    # remove regardless (verify the app after!)
#         APP=/path/to/Foo.app ./00-slim-qt.sh
