 * rendered permanently, position:fixed and inset:0, over the whole app, with
 * the seat dialog on top because it is declared last. Its <select> was empty
 * because openSeatModal() had never run - and openSeatModal() is the only
 * caller of loadCatalog(), so the model list was never fetched either.
 *
