Previous build still had ~25px of dark padding above the screenshot
plus a thin shadow border around it. Both gone now. Screenshot is
flush against the top edge of the frame and runs full-width; the only
remaining chrome is the 90px caption bar at the bottom with the green
checkmark and detector verdict.
Net effect: roughly 25-30% more usable screenshot area per frame, no
visible "bar" above. Size 478 KB (was 381 KB, larger because the
embedded pixels are now bigger).
