/*
 * IO-31583 Modern product filter layout.
 *
 * Authored mobile-first: the unprefixed rules below describe the phone layout
 * (a slide-out drawer), and the min-width blocks progressively promote it to a
 * sticky desktop sidebar. There are deliberately no max-width queries here.
 *
 * Everything is namespaced under .io-filter so this file is inert on sites
 * still using the classic layout.
