The counter was its own last body line, and the pinned day-divider
header reserves the top viewport row without relaxing the bottom scroll
clamp - so exactly when the transcript filled the screen, the counter
fell off the bottom. The budget now trails the compose text inline
(wrapping along with it, costing no row), and the frame slides the
window down a row when a sticky header is pinned at the very bottom,
so the last body line always wins over the duplicate heading.
