Seedance 2.5 Global API

# Text-to-video. A prompt is all it takes — length and resolution are NOT
# parameters on this tier: every clip comes back 30 seconds long at 720p.

# With reference images — up to 9, as public HTTPS URLs.
# images / image_urls / reference_image_urls / image are aliases for the same list,
# so a request migrated from seedance-2.5 keeps its reference images.

# Each of these is rejected with a 400 at create time. Nothing is quietly
# rewritten to 30s / 720p and then billed the full $2.00:
#   "duration": 10                → 30 seconds is the only length
#   "resolution": "1080p"         → 720p is the only output
#   "reference_video_urls": [...] → no video editing, no extension
#   "task_type": "edit"           → same, use seedance-2.5 instead
