# fix-gtk4-dark.sh — point ~/.config/gtk-4.0/gtk.css at the dark Breeze
# GTK4 stylesheet so GTK4/libadwaita apps follow the dark desktop theme.
#
# Background: KDE's GTK sync (kde-gtk-config) symlinks gtk.css to the
# LIGHT Breeze stylesheet. GTK loads that file at user priority, which
# overrides libadwaita's dark mode, so GTK4 apps render light no matter
# what. KDE may rewrite the symlink whenever "Apply" is hit on the
# GNOME/GTK Application Style settings page — re-run this script if
# GTK4 apps go light again. Restart affected apps to pick up the change.
