Seedream 3 prompt-only image generation with size and guidance controls.

Seedream 3 is the older text-to-image Seedream node. It exposes seed, size, custom width and height, aspect ratio, and guidance scale.

Use it when a straightforward prompt-only Seedream generation is enough. Use Seedream 4, 4.5, or 5 Lite when reference input, editing, or newer high-resolution behavior matters.
