     the whole menu the way an <a> click handler would.)
     Two height mechanisms, layered:
     1. Base (all browsers): max-height 0 → capped value. The cap only needs
        bumping if the submenu ever outgrows it AND the visitor's browser
        lacks :has() — modern browsers ignore it entirely (see 2).
     2. @supports selector(:has(*)) below: grid 0fr→1fr animates to the true
        item count, so the open height always fits however many products the
        submenu holds. Gated on :has() because the open state needs it — a
        browser without :has() would otherwise be stuck at 0fr (clipped shut),
