Settings -> Data picks the PC backup folder (e.g. a cloud-sync folder; old folders stay listed) and turns on
automatic snapshots (off by default): Quest launchers snapshot the saves when the game closes, under the launch lock,
keeping the newest three changed ones on the Frame, and FramePort imports them as automatic backups when it connects.
Agent v101. Checked on the Frame with BlazeRush (snapshot per close, one import per snapshot).
