Seedance has no negative_prompt — phrase exclusions as positive constraint phrases at the tail (e.g. “do not generate a watermark”, “keep it subtitle-free”).
There is no negative prompt on this family; write exclusions as positive constraints.
Weight syntax such as (word:1.3) is ignored; it only wastes prompt space.
Keep to at most 4 distinct characters in one prompt.
