ludic.ui: an override's path is compared normalised, and an absolute path matches the relative one it ends with - a lab build registers its components as lab/../src/ui/..., so the studio's src/ui/... (or absolute) path matched nothing and the override changed nothing; nothing is normalised while no override stands; examples/library/ui_override_up registers under a .. path as the lab does
