The viewer alone, on the same comp document the sandbox lands on. Four cases, because the design draws four: the list in a settings rail, the list in a column, the graph in that column — a spine-only preview, because §16b says the arcs and both gutters cannot be drawn legibly there — and the graph expanded to full width.
Below them, §16g's panel states and §16h's day-one repository. The clock is fixed here, so every panel is a reproduction rather than a moment — which is why none of them offers a refresh, with one exception: §16g draws the stale stamp with its inline refresh, and a stale panel missing the affordance the frame draws cannot be judged against it.
