// Opens FILE in the Files viewer on MACHINE ("hub" for the hub itself), plays it on Auto,
// checks the 360 view if it is one, seeks into the middle, picks the lowest quality, tries
// Original, and reads the menu's "Made on …". Changes nothing. DEVICE="Pixel 7" for a phone;
// TRACE=1 prints every piece asked for. Screenshots land in $SHOTS (default /tmp/hamlab-shots).
