Use saved characters (@Name)

This model takes no reference images, so @Name of a saved character is refused (400) before anything is charged. A saved location, prop or style with a description is inserted as text. For saved characters, use a model that takes reference images, such as Nano Banana Pro or Seedream 5 for images, or Seedance 2.5 or WAN 3.0 for video.
