Three faults, all visible on a phone at once.
Two hamburgers, neither useful. The assistant added a drawer button of its own
AND the app's button was still there, stacked on top of it. Worse, the assistant
hid the app sidebar unconditionally, so the app's button opened something
invisible. A phone now has exactly one menu — the app sidebar — and the assistant
only replaces it with its own rail on desktop.
The collapse control had nothing to collapse on a phone, where the menu is a
sheet rather than a rail. It closes the sheet instead.
Sources were `display:none` below 640px with no alternative, so every SRC chip in
an answer pointed at nothing. They now slide up as a dismissible sheet, opened by
a button that appears only when an answer actually has citations, or by tapping a
citation itself. Tapping away or pressing Escape closes it — a sheet with no way
out is a trap.
The menu itself is sized for a thumb, borrowing the reference layout: a wide
sheet, close and search leading, tappable rows, and padding clear of the home
indicator.
