echo "Drop Kvantum now that Qt apps follow the theme through the GTK platform theme"

# QT_STYLE_OVERRIDE is gone, so Kvantum is no longer painting anything -- Qt

# falls back to built-in Fusion and takes its palette from

# QT_QPA_PLATFORMTHEME=gtk3, which actually tracks the Omarchy theme. Kvantum

# never did; we have never shipped a .kvconfig for it to read.

# kvantum-qt5 has to go in the same transaction: it is the only thing that

# requires kvantum, so removing kvantum alone fails the dependency check. It has

# been dead weight since VLC was retired anyway, and it takes qt5-svg and

# qt5-x11extras with it.

# What this deliberately does NOT touch is qt5-wayland and qt5-declarative. On a

# machine whose sddm theme metadata predates QtVersion=6, those are what keep

# the Qt5 greeter able to start, and removing them is how you end up with no

# login screen. qt5-wayland is explicitly installed, so the -s cascade leaves it

# and the qt5-base beneath it alone.
