/*
 * Full-screen menu (below 1024px; parts/site-menu.php, site-menu.js).
 * One Forest screen under the fixed bar, like a page of the site: the main
 * menu in Subheadline-size Brando, Cooper 1, with the bar's 6px hover line;
 * Reserve in Hillside; the contact details in the menu type at the bottom.
 * The panel is a fixed sibling of the header, under the bar and its blur
 * (z-index 48 < 49 < 50) and above the page, so a page transition treats it
 * as part of the old page and the new page slides up over it.
 * Open: the screen fades in, then the links rise one by one from a clip mask
 * (the heading reveal of reveal.css, same timing). Closed: hidden.
