What you type is a bubble of its own kind — the cloud's shape in a pink tint with dark pink ink — and a run of typed lines is one bubble, not a stack of pills. Corners are cut on the slant with the triangles; `corners: block` in the layout keeps the stepped quadrants for a font without them. Tools and subtasks show as provisional rows at the foot of the page while they run, one line each, and vanish as each one finishes; nothing of them is kept on the page.
