(1m 49s + 2.2k tokens - thinking with medium effort) All six stills are 1320x2868 (6.9" iPhone) and the video sits inside Apple's 15-30s window. Note on the current look: the studio's goldie/goldie.design.json overrides the config with the editorial template, a silver 17 Pro bezel, and a blue gradient, so that's what rendered - not the orange/cream values still sitting in goldie.config.ts. If you want the blue-and-silver look to be permanent, say so and I'll copy those three values into the config; if you'd rather have the orange back, deleting goldie.design.json and re-running frame does it. Cooked for 2m 3s - done 3:26 PM. 1 shell still running
    Camera
