TUI-C40 — the resting face, under the name the animation layer refers to it by.
Every frame below is the same five lines and the same 16-column field, so swapping one in changes nothing about the layout: the right column still starts at RIGHT_COLUMN and the truncation budgets are untouched. That invariant is what makes an animation a data change rather than a geometry change, and it is asserted per frame in the specs.
