# FIGHT NIGHT, Vertical One-Take (20 s): FUENF Etagen, NUR Kamerabewegung von unten nach oben (Tariq 05.09.2026, "Anfang mit Auto").
# Turm bei x=40, Held immer bei (40, 0). Etage 0 = Strasse am Hintereingang mit SUV (Boden 0, Betondach der Rampe 4,5..5),
# 1 Gym (5), 2 Eisbad (10), 3 Kreis (15), 4 Arena (Boden 20, Canvas 21, Truss 25,3..25,8). Platten 0,5 m, Schnitt im Dunkel.
# Kamera-Saeule (43,3, -3,3) fuer alle Etagen, identische Bewegung je 4 s, Rig crane.
