/* ==========================================================================
   menu.css — Staggered overlay menu
     · Two-step open: panel slides down, items stagger in
     · Two-column layout (links + preview image) collapses to one on mobile
     · Hover lifts the number, slides the row, fades a different preview image
     · Works LTR + RTL because every direction-sensitive thing uses logical
       properties or transforms (which are direction-agnostic)
