Seedream 5.0 pro exclusive capabilities (new)

• Interactive Editing: Supports specifying edit positions via coordinates, bounding boxes, arrows, and other methods to precisely edit images, enabling fine-grained operations such as local element replacement, object localization, and regional generation.
• Layer Decomposition: Supports automatically decomposing a single image into 1 base image and up to 16 independent layers with transparent channels (subject, background, text, decorative elements, etc.), making secondary editing such as moving, scaling, replacing, and color grading easier.
