/**
 * Fullscreen overlay for the native WooCommerce Product Search block
 * (core/search block, buttonPosition = "button-only", used in the header
 * template part). The block already ships an accessible expand/collapse
 * behaviour driven by the WordPress Interactivity API: it toggles the
 * "wp-block-search__searchfield-hidden" class on the form and reflects the
 * open state through the button's aria-expanded attribute.
 *
 * IMPORTANT: the fullscreen overlay styles below are intentionally keyed to
 * "html.has-search-overlay-open", a class the JS enhancement adds/removes -
 * NOT to the form's own "wp-block-search__searchfield-hidden" class. If we
 * keyed off the form's own class directly, the overlay would vanish the
 * instant WordPress toggles that class, and the block's own default
 * (non-overlay) transition would then play at full viewport size before
 * shrinking into the header - a visible glitch. Routing through a class the
 * JS owns lets the JS also kill transitions for one frame on close (see
 * ".has-search-overlay-no-transition" below), so nothing animates at all
 * when the overlay is dismissed.
 *
 * Closed state : html without .has-search-overlay-open
 * Open state   : html.has-search-overlay-open
