Four scenes, recorded and looked at frame by frame:
- library-labels: 6, 7, 8 and 9 over four New York frames, 7 again to
take one off, then the Green chip narrowing the grid and back.
- compose-perspective: two towers shot from below, stood upright with
Vertical at about +58, then held against Before.
- crop-orphan: a stroke in the top-left corner, a crop that leaves it
outside, the notice with Undo crop and Keep crop, and Undo crop.
- local-intersect: a linear gradient over the lower half, then
Intersect and two strokes that survive only where it is.
develop-zoom already ends on hard-edged pixels (previous commit). The
text added is a sentence or two under the existing headings, so the
other branch's structure and anchors are left alone.
