NFR-P11's criterion was "no dropped frames, no state loss" across a layout
class transition. Read literally, the interface already fails it, and fails it
by design: `apply_layout_class` clears the user's panel open/closed choices
whenever the class changes, and `PanelChoices` documents why — a choice made in
landscape answers a different question from the one portrait asks, and carrying
it across leaves a 232 px sidebar on a screen with no room for it.
A requirement that the code deliberately contradicts is worse than no
requirement, because the next person to read it either "fixes" the behaviour or
learns to discount the register.
So the criterion now names what must survive — the open image and version, the
selection, scroll position, the in-progress edit and its undo history, the
current mode — and states the exemption with the reasoning attached. Panel
disclosure is a default re-derived per class, not state; the user's
disagreement with it is remembered within the class where it was expressed.
The intent is unchanged: a resize must not cost the photographer anything they
did. It is now possible to write a test for that.
