A kilometer-scale carrier hangs in frame, launch bays glowing. Six small interceptors pour out in formation.\n\nShot 1: Slow crane down from the carrier's hull. Interceptors accelerate outward in a tight V-formation, exhaust trails curling against the planet's cloud bands.\n\nShot 2: Cut to medium chase shot behind the lead interceptor. It pitches up slightly, weaving through drifting orbital debris shields—movements smooth and controlled, not violent.\n\nShot 3: Wide static hold, then gentle push-in. The swarm spreads into attack spread as a distant enemy silhouette flickers on the horizon—one brief red warning glint on a HUD reflection in the canopy.\n\nConstraints: stable proportions, realistic space physics feel, smooth motion, no subtitles, no watermark, no logo.",
