 * The three full-viewport overlays below (#nx-mega-menu / .nx-search-modal /
 * #nx-bookmarks-drawer) each ship `display:flex` plus
 * `position:fixed; inset:0; z-index:70; background:rgba(0,0,0,0.8)`, so with
 * `hidden` defeated all three painted at once over the whole site --
 * 1 - 0.2^3 = 99.2% black. The entire page rendered as a black screen on
 * every device while the DOM underneath reported itself perfectly visible.
 * This guard makes `hidden` actually mean hidden, for these and anything added later.
