Declare FollowsColorScheme=true for the Shift icon theme so KDE apps recolor symbolic Places glyphs against dark and light surfaces. Document the requirement and guard it in the icon theme coverage test.
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.
