- Add qt-theme-set: a working Qt theming pipeline via qt6ct (the
QT_QPA_PLATFORMTHEME=qt6ct env var was pointing at a platform theme
plugin that wasn't even installed, so every Qt app fell back to its
own default style). Also regenerates kdeglobals' KColorScheme groups
and sets QT_QUICK_CONTROLS_STYLE=org.kde.desktop for Kirigami-based
KDE apps, whose QML-drawn chrome ignores QPalette/qt6ct entirely.
Gwenview's dialogs/content now follow the theme; its toolbar/statusbar
chrome is a known remaining gap tied to Kirigami's platform-theme
detection outside a full Plasma session
- Add GTK2 compat (~/.gtkrc-2.0: icon theme + font follow the theme;
no dark variant exists for GTK2's Adwaita engine)
- Add modules/default-apps.nix: Gwenview/Ark as system-default image
viewer/archive manager via /etc/xdg/mimeapps.list, LibreOffice
(Qt6 build), and a working Thunar "Open Terminal Here" (it shipped
calling exo-open, which isn't installed and never resolved)
- Fix display-set.sh: mktemp defaulted to /tmp, a different filesystem
than ~/.config/hypr here, making the mv into display.conf a
non-atomic copy+unlink. Hyprland's file watcher could catch it
mid-replace and throw "source= globbing error: found no match" on
any monitor mode/orientation change. Stress-tested with 60 concurrent
write+reload cycles after the fix with zero errors
