Writes structured Seedance video-generation prompts with image-reference anchoring, timecoded shot lists, identity-continuity rules, cinematic color grading, and natural-sound direction. Use when the user asks for help with Seedance prompts, AI video prompts, text-to-video scene descriptions, cinematic video prompts, or any request to script a short generated film shot-by-shot. Trigger whenever the user mentions Seedance, video generation, text-to-video, AI video, shot list, scene prompt, or wants to turn a still concept into a timed video brief — even if they don't say "Seedance" by name.
