# Verify that the patched checkout still is Modrinth Enhanced.
#
# A patch can apply cleanly and still stop doing its job - upstream may move
# the thing it was holding down. These checks assert the outcome rather than
# the diff: the app is named correctly, offline accounts exist, and no
# telemetry endpoint survives into the built frontend.
#
# Checks that need the built frontend are skipped when it is not there yet, so
# this is useful both before and after scripts/build.sh.
