/*
 * Site header (template-parts/site-header.php), as in the Header wireframe.
 *
 * The header runs the full width of the window, with a 48px gutter each side (24px on tablets, 16px on phones).
 *
 * Desktop: the logo on the left; on the right, the contact row above the main navigation and the booking button.
 * A menu item with sub-items (Services) opens them as a full-width bar under the header.
 *
 * Phones and narrow tablets (980px and under): the navigation tucks behind the menu button once the script runs
 * (.has-js), and each item's sub-items are listed under it inside the menu. Without the script, the navigation
 * and its sub-items show in full.
