The same lab twice, in two boxes. The left one is the circles board — Stained Glass Circles as its story page mounts it (since R4, 24 Oct 2026; before that the lab at the circles level): a tap inside a shape colours it, and its column is the window profile's. The right one is euclid, which is the lab as it hangs in the gallery. Draw in one, then the other; undo in one must not touch the other.

What to look for: the tip window, the picker, the colour window and the replay panel stay inside their own box (Remember is not on screen until Maya is); a drag that leaves the box still moves the thing being dragged; Cmd-O opens the picker only in the box last touched; both boxes read the same saved library, because it is hers.
Below the boxes this paragraph is in the page's own Georgia and colour, which the module must not have changed.
