/* HTML `hidden` attribute is authoritative. Author rules like
 * `.login-screen { display: flex; }` otherwise beat the UA
 * `[hidden] { display: none }` baseline because they share
 * specificity (0,0,1,0) but come later in the cascade — which is
 * exactly the bug CCP flagged against the first deploy of this
 * console, where the login overlay stayed visible over a fully-
 * authenticated dashboard. `!important` here re-asserts the HTML
 * spec semantics against any future author rule that forgets about
 * the attribute. */
