/**
 * One runtime the whole catalog can be seen under.
 *
 * Some products are not one product. The same build runs embedded in a host
 * application and on its own, and the difference is not a state inside a screen
 * — it decides which screens exist and what each one is allowed to show. A host
 * that declared such a runtime had nowhere to put it: an axis belongs to a
 * frame, and a preview control only dresses the live preview, so the catalog
 * could only ever be captured under whichever runtime happened to be the
 * default. The other one was invisible.
 *
 * A session preset is that choice, made once for everything. Selecting one
 * rewrites the storyboard baseline, which every frame's identity already folds
 * in, so the catalog re-resolves under the new runtime instead of showing
 * frames captured under the old one.
