Audit follow-up: the deferred 'dead .sidebar/.nav-link residual' was broader than
logged (OtOpcUa's site.css duplicated and overrode the whole kit shell). Pruned
across all 3 apps on chore/theme-css-prune branches (-167/-95/-106 lines, builds
clean). Note the remaining deferred items (kit layout.css calc review; ScadaBridge
Host transitive kit ref) and reconfirm the Theme 0.2.0 publish is genuine.
