/**
 * PUBLIC CATALOG — THE MOBILE NAV: the click-catching overlay, the slide-out
 * category drawer (parents, chevrons, expandable subcategory lists), and the
 * two narrow-width blocks that reshape the HEADER and the drawer together.
 *
 * SECOND of ten sheets — after styles.css (tokens, reset, header), before
 * styles-page.css. Read the load-order block at the top of styles.css before
 * moving a rule between sheets: the split is a contiguous slice of one original
 * file and the cascade depends on it.
 *
 * The <=768px and <=720px blocks at the bottom restyle `.header`, `.search-box`
 * and `.menu-btn` as well as the drawer. They live here rather than with the
 * header in sheet 1 because that is where they were in the original, and
 * because the mobile header and the drawer are one design: the bar collapses
 * so the drawer can take over.
