Kling 2.5 Turbo (pro)
Camera: behind the walkers, follow at their pace, no steadicam flourish. Picture: Split-flap or 2001 LED board ticks one destination. Payphone caller does not hang up. Roll-aboards track true. Must not: TSA body scanners, 2020s branding, boarding panic. Foley: wheels on terrazzo, flap-clack, muffled unintelligible PA, a zipper, distant jet only as room tone — not a flyover. No music.
