On a phone, a conversation dragged to the right shows a red bin behind it;
let go past a third of the row and it goes to Trash, short of that it
springs back. Vertical drags still scroll (touch-action: pan-y), and a swipe
never opens the conversation. "Moved to Trash · Undo" shows for 5 s and the
move is made only after that, like Undo send — so Undo just shows the row
again; leaving the page still deletes. Not in Trash (it would be for good)
and not offline.
The ⋯ menu on a phone gains Mailbox display, holding only "Show a dividing
line between rows" (a phone has no layouts to choose).
The corner toast takes an optional action (label + run) and duration.
