 * right:0/inset:0 (the drawer, the modal/drawer backdrops) can resolve
 * against the resulting wider LAYOUT viewport instead of the true visual
 * one, and end up rendered partly or fully off-screen. This is real mobile
 * browser behaviour, not just a testing artefact. One overflowing row
 * anywhere on the page can make the drawer's own close button unreachable.
 * Hard stop, so a future addition can't silently reintroduce this. */
