Landscape phone (720-1000px band) put the parent grid at 2 columns while the
tile spans (hero span-2, full span-3) only reset at 720px. A span-3 tile in a
2-col grid forced a phantom 3rd column and collapsed the 1fr tracks to
58px 58px 760px, squishing the flagship card to ~132px off the visible area.
Move the span reset to the same 1000px breakpoint the grid drops to 2 columns:
now 446px 446px, hero full-width. Desktop 4-col + portrait 1-col unchanged.
