# install-notif-clear-fix.sh — idempotent. REQUIRES ROOT (writes the package-owned
# shell file under /etc/xdg).
#
# Fixes the NoSignal notifications popout "Clear" button, which did nothing
# (called n.notification?.dismiss() instead of n.close(); see README).
#
# NsNotifications.qml is shipped by the `nosignal-shell` package (baked into the
# fork). The REAL fix is in the fork source — this fallback patch is for already-
# installed boxes and is reverted by the next nosignal-shell upgrade (which will
# carry the fixed file). The builder bakes the fix into the fork and sets
# NOSIGNAL_SKIP_SHELL_PATCH so this step is skipped there.
