Seedance video prompting

ByteDance's Seedance family generates video and audio jointly and takes multimodal references (images, video clips, audio clips) that a prompt addresses by label. Getting the labels and the task type right matters more than adjectives: the same sentence can be read as "reference this" or "edit this" depending on one word.

Load reference.md for the full formulas, the failure table, worked examples and the ComfyUI parameters. Load supplementary.md only for non-official leads about 2.5; it never overrides reference.md and carries a conflict ledger. This file is the router and the rules you need before writing a single line.
