/**
 * The storefront notice bar (OW-038): an empty container that the status
 * script fills while ordering is closed or paused.
 *
 * PHP prints only the empty, hidden container (and asks for the script), on
 * every page in scope whatever the store's state now, so a copy of the page
 * cached while open still shows the bar once the store closes. The message is
 * never in the HTML: the script puts the closed message from `GET /status` in
 * with `textContent`, and hides the bar again when the store opens, when the
 * setting is turned off, or when the shopper dismissed this state.
 *
 * Placement: at `wp_body_open`, in the normal page flow above the theme's
 * header. A theme that never fires `wp_body_open` gets it at `wp_footer`, as a
 * bar fixed to the bottom of the window. Order-pay and order-received pages
 * never get it (paying an existing order is allowed while closed, D1).
