preview: Staircase stops borrowing Classic's arrangement. Under the Staircase look the conversation is drawn the designer's way: your bubble is the ink itself with the paper as its text, everybody else's a warm grey, a tail corner on the last bubble of a run, runs closed up and the gap where the speaker changes opened out, a line the room writes itself centred bare, and the day in a serif italic beside the time. Group avatars are arched doors, an unread count a plain door-light capsule, chat rows parted by a hairline, the chosen tab drawn without a pill, and the send button lights up when there is something to send. Classic and Ink & paper are unchanged. The screen-layout rows of the pack are pack 03.
