Coming back from the studio on a phone left the grid where it was: the
frame the studio was holding was lit by nothing and looked for by hand.
The shelf already stamps the frame it was left on and the wide screen
already opens on it; the phone's grid never read it.
The stamp travels down as a landing, and the grid lights that frame,
walks the list out to it when it sits past the rows drawn so far, and
scrolls it under the eye. Each landing is spent once, so a list that
changes under the reader is not dragged back to it.
probe-mobile-return.mjs, on a phone: the frame the studio held is the one
lit and the one in view, both when it is at the top of the shelf and when
it is buried past the first window.
