/**
 * core/navigation — desktop dropdowns, mega panels and the mobile overlay.
 *
 * Core's stylesheet collapses a closed submenu to width:0/height:0 and sets
 * min-width:200px again inside its own :hover rule, so every sizing rule here
 * has to live in matching open-state selectors with higher specificity — a
 * base-state min-width silently loses. Desktop rules are prefixed with
 * `.wp-block-navigation__responsive-container:not(.is-menu-open)` so none of
 * them leak into the mobile overlay, where hover never happens and a
 * hover-driven reveal would leave items invisible.
