The Save button is gone, and so is the SaveTarget context that announced it.
Every screen here is a preview of the thing being edited, so a change is already
visible before it is written — a button then asks somebody to confirm what they
can see.
useAutosave debounces a burst into one request. It takes the unsaved state as a
string rather than a flag, so a failed save is not retried on the next render,
and it flushes on unmount so a section change loses nothing.
