Found via a fresh-install test in a QEMU VM using the repo's answerfile
system (hyprlua, tablet/touch eww bar variant).
1. hyprlua.sh/hyprland.sh/niri.sh all compile EWW (GTK3) from source but
never installed gtk-layer-shell — only gtk4-layer-shell, which is a
separate package for astal-menu's GTK4 surface. Every fresh install
failed at the gtk-layer-shell-sys build script with a pkg-config
error ("gtk-layer-shell-0 ... was not found").
2. The EWW `git clone` isn't idempotent: a leftover ~/install-tmp/eww
from an earlier interrupted/retried install (e.g. the failure above)
makes the next clone abort with "already exists and is not an empty
directory", killing the whole script under set -e. `rm -rf eww`
before cloning fixes retries.
Both reproduced and fixed directly in the test VM before being applied
here: installing gtk-layer-shell and clearing the stale checkout let
the same run complete successfully.
