Create a clean process film showing final assembly of one fictional aluminum desk fan at a small workshop. Preserve the workstation, jig, torque driver, four fasteners, fan housing, grille, cable, worker identity, and PPE from the references.

Show four verified steps: seat the motor housing in the jig; route the cable through the existing channel; position the grille using its alignment notch; tighten four fasteners in the approved cross pattern. Use close views for contact points and a stable overhead view for the pattern. The driver stops after each fastener; do not show a torque value unless added later from verified production data. End with the unpowered fan on the inspection mat while the worker checks grille clearance by hand.

Sound intent: workshop ambience, part contact, four driver stops, no voiceover. Keep part count, tool geometry, cable route, PPE, and machine state continuous. Avoid spinning blades, missing guards, invented efficiency claims, logos, readable serial numbers, extra hands, sparks, or watermark.
