/*
 * StudyFlow — Midnight Aurora redesign
 * A cool, vivid, glass-forward visual language layered over styles.css and
 * theme-refresh.css. Indigo / violet / cyan accents with serif display type
 * and soft layered shadows. Pairs with glass-morphism.css for the frosted UI.
 *
 * Loaded LAST so it wins cascade. Does not change markup or JS behaviour.
