Kirigami.Icon { isMask: true } flattens an SVG to its alpha, so when a quick-setting tile resolves to a colored preferences/scalable glyph the whole rounded background collapses into a solid square. Append -symbolic to the five icon names that collided with colored tiles and add symlink aliases where no real symbolic variant exists yet. Guard the regression with a check in tests/check-shift-icon-theme.sh.
BusyBox find does not support GNU find's -xtype predicate, which
caused shift-icon-theme-coverage to fail in CI. Iterate symlinks with
portable find -type l -print0 and let Bash check whether each target
exists instead.
Install org.shift.icons as the look-and-feel icon theme while keeping the Plasma style on breeze-dark. Add the icon-theme coverage guard and CTest registration so shell, System Settings, KCM, and installed Plasma icon names do not silently fall back to missing Breeze-only assets.
Document the theme rules and add scoped REUSE metadata for the Phosphor-derived SVG glyphs.
