/**
 * FIXME: Temporary Night-mode override classes
 * Remove these once T363849 has been addressed.
 *
 * The following classes are meant to force OOUI interfaces
 * into light-mode when night-mode is enabled. They should be
 * grouped with the `.notheme` rulset as an alternative to
 * using the `.notheme` class in multiple places.
 *
 * Note: These are wrapped in quotes to avoid dashed being interpreted as minus signs,
 * along with a `~` to unwrap them when they are used as selectors.
