A view rect that composes with the crop in the same normalised space:
nesting one rect in the other is a multiply, so the shader needs no second
rect and no extra uniform slot.
Zoom is explicitly not an edit. It is excluded from is_active, from the
structure hash, and from the sidecar, so a zoomed view exports exactly as an
unzoomed one does. is_neutral now asks the framing whether it *edits* rather
than whether it is active — otherwise merely zooming would mark a clean file
dirty.
Because the render target keeps its size while the sampled region shrinks,
zooming raises the resolution the pipeline works at rather than magnifying
already-rendered pixels, which is what makes 1:1 inspection show real detail.
