The studio is where a frame is graded, and the frame next to the one being
graded is the one the reader almost always wants next — a roll is shot in
order and looked through in order. Until now the only way to it was LIBRARY:
the stage had no way back to the folder the frame came from.
The strip stands between the photo and the row that names the file, on the
phone at the same place. It holds the folder the open frame was filed in —
the frames beside it, not every frame the folder was scanned for, which is
what the row's own `dir` is read for — in a file browser's order rather than
the catalogue's newest-shutter-first, because a roll off a camera is the
order it is looked through in. The frame on the stage is the lit one and the
one the rail is scrolled to, wherever the rail had been left; a click is the
same opening the catalogue's wall makes, so the frame arrives with the look
it was last left at.
The tiles are the shelf's own: `makeThumb` off the same store, and the URL
cache the wall keeps is lent to the strip through the hook that fills it.
