A composer that unrolls from a hairline, writes a brief into itself while the camera cuts in and rides the caret, then cuts back out to the send button as a pointer arrives and clicks it. The typing is eased, not constant — 17 chars/sec on the first word, 33 in the middle, a settle on the last three. Long copy scrolls the field under its own caret and extra suggestions wrap, so the panel fits whatever you put in it.
