How X Works — explain how something works with clean diagram visuals

A finished reel = vertical 9:16 + voiceover + music + ~45–90s. Pass `aspect_ratio: "9:16"` to `generate_project` (it now threads to every scene), set the i2v `duration` to 8–15s on EVERY scene and animate all of them, add `inworld-tts` narration (not the chatterbox default voice) + `music`, and mux the bed with `audio_fill:"loop"` so the score covers the whole reel. A silent landscape montage — or one whose music cuts out partway — is a draft, not a deliverable. See the `short-form-video` skill's *definition of done*.
