Shade drag-to-close (board check)

Evidence class: board webcam recording with injected touch, not a real finger. Captured 2026-09-25.

The tray’s edge was tracked per frame along one camera row (x = the strongest light-to-dim step):

Phase (video time)What was measured
Slow close, 4.3–9.2 sEdge moves steadily 810 → 363 px with the finger, then leaves the measured span. Mean brightness rises gradually (126 → 143) as the backdrop fades through the release settle. No jumps.
Short drag, 20.0–21.5 sEdge follows to 713 and holds. On release it eases back open: 723, 769, 797, 808, 810 on consecutive frames.
Backdrop tap, 23.90 sThe sheet closes over about 3 frames (811, 724, 403, gone).

Not obtained: a real-finger session, and a fling-velocity close.
