/* ---------- Responsive ----------
   Budget board must keep 5 equal columns on one row on every desktop/laptop
   width (1440/1366/1024) and only ever step down to 2 (tablet) then 1
   (mobile) — never a wrapped 3+2. The sidebar is dropped for the bottom nav
   a bit earlier than the 2-column breakpoint so a 1024px laptop still has
   full content width to fit 5 columns comfortably. */
