OpenLIFU-app's dark theme (Home.qss) styles most widget types automatically via type selectors (QPushButton, QComboBox, QTableWidget, etc.), but some elements need an explicit opt-in via a cssClass dynamic property to pick up a specific visual treatment beyond the default.
Multiple widgets can share the same class; the base widget type is left unstyled otherwise, so this is purely additive.
