Overlays
The small dialog that appears above an open sheet (or page) when you try to leave with unsaved edits: Keep editing, Discard, Save and close.
Lifted from the approved family page at build time; interact with it.
Only when something changed. Keep editing is the default and holds focus; discarding is the quiet red one.
You changed Stone linen jacket. Closing now loses those edits.
