/* ============================================================================
 * Snaplot — shared App Tabs bar
 * ----------------------------------------------------------------------------
 * Rendered at the top of /catalogue/, /bulk-upload/, /mailroom/ to make all
 * three flows feel like one app with three tabs. Each tab is a real <a>
 * link — clicking navigates between pages. The current page's tab gets
 * .is-active.
 *
 * Catalogue selection is preserved across tabs by reading
 * localStorage.snaplot_catalogue and appending ?catalogue=<name> to each
 * tab's href.
