Two things the preview owed a reader.
The frame raised in the strip outlived nothing: leaving for the studio and
coming back dropped the choice and the node opened on its first negative
instead. It is now remembered beside the folder and the column width — the
same one-line store, read on the way in, written on the way out — and a
frame that is gone from the catalogue falls through to the first, the way
a node that is gone falls back to its folder.
A wheel over the frame now magnifies it. The listener goes on the element
rather than through onWheel, because React's own wheel is passive and this
one has to hold the page still while it zooms; the origin is the point
under the pointer, which is what keeps a reader's aim on the thing being
looked at, and the step comes from how far the wheel turned so a notched
mouse and a trackpad travel the same. Six times is where it stops — the
thumbnail behind the preview has no more pixels to give — and a frame that
has just come up is fitted again.
library-check: 35 steps, the two new ones raising a nested frame, reloading
on it, and ticking the wheel up and back down.
