# Dev setup: install the SYSTEM packages Kasual Desktop runs against. There is no
# venv — Kasual must use the distro PyQt6 (version-locked to KDE's layer-shell
# plugin; pip's bundled Qt cannot load it). The .deb/.rpm declare these same deps
# (see nfpm.yaml); this script just sets up a from-repo dev checkout.
