Adds demo-vehicle to the camera list and the visual targets, plus shot 9 in Screenshots/README.md - marked FAIL, because that is what it shows. The vehicle is staged and runs: spawned at (-12950,-900,120), 9 visual panels attached, panel 0 visible with a 238 cm extent, settled at Z 119 cm. The capture shows an empty road with a soft shadow. Two checks disagree in a useful way: visual_loop --verify PASSES the frame (it only tests size, blankness and tonal range, so a well-exposed empty road passes), while judge_screenshot returns verdict=no confidence=1.0. Strongest clue, recorded in TODO.md: a downward trace from the vehicle finds no ground at all (ground at Z -9999), so the car sits over a surface without collision or inside geometry - the shadow and the panels are not in the same place. Diagnostics added along the way: mesh/visibility/bounds at BeginPlay, per-panel world positions and extents, and the ground trace. The visual panels were also unhidden from the physics mesh: SetVisibility(false, ...) hid them whether or not propagation was requested.
