HiAPI Seedream 5.0 Pro

Use this skill for both HiAPI models:

• seedream-5.0-pro/text-to-image (alias t2i, default): text-to-image with strong poster, signage, calligraphy, product, and portrait rendering.
• seedream-5.0-pro/image-to-image (alias i2i): edits and multi-reference compositions using 1-10 reference images.

The current request contract uses quality, not the removed resolution field. Both models use the same eight aspect ratios; do not send match_input_image or auto.

Requirements

• Node.js 18 or newer.
• Set HIAPI_API_KEY in the environment.
• Optionally set HIAPI_BASE_URL; the default is https://api.hiapi.ai.
