#
# Mask the pressure axes with a quirks override, same pattern as the
# Asus UX302LA entry in libinput's shipped 50-system-asus.quirks.
#
# Two things matter for the override to take effect:
# 1. libinput reads only ONE override file, /etc/libinput/local-overrides.quirks.
# Custom-named files in /etc/libinput/ are never loaded.
# 2. udev tags this pad as ID_INPUT_MOUSE, not ID_INPUT_TOUCHPAD, so a
# MatchUdevType=touchpad section is skipped. The bus/vendor/product/DMI
# keys already pin the device exactly, so we omit the type constraint.
