Timeline Photo Strip

Ordered stations (four 240×160 photos by default) alternate above and below one timeline with date captions on the line side; the camera pans station to station (0.9s move + 1.0s hold, dock zoom 1.05 so neighbours clearly leave frame, current station 1.03 bright / others .7) → pulls out to z .62 to show the whole strip, holds 1.2s on purpose → exits with the text
