Use the SeedRouter API to generate a Seedance video for me.

Security: read SEEDROUTER_API_KEY from my local environment. Never ask me to paste it and never print it.

Goal: [subject, action, camera move, lighting, what the clip is for]
Model: [dreamina-seedance-2-0 | dreamina-seedance-2-0-fast | dreamina-seedance-2-0-mini | dreamina-seedance-2-5]
Resolution: [480p | 720p | 1080p | 4k]    Ratio: [16:9 | 9:16 | 1:1 | adaptive]    Duration: [seconds]
References: [public image, video or audio URLs with their roles, or none]

Send POST https://api.seedrouter.ai/v1/contents/generations/tasks with
{"model": "...",
 "content": [{"type": "text", "text": "..."}],
 "resolution": "...", "ratio": "...", "duration": 5}
Media goes in content as image_url, video_url or audio_url items with a role,
never base64. Do not add fields that are not in the API reference.

Before sending, show me the request body and wait for my approval: each
task is charged. Then poll GET https://api.seedrouter.ai/v1/contents/generations/tasks/{id}
every 15 seconds until status is succeeded, failed or expired. If polling
times out, keep checking the same task; never resubmit. Save
content.video_url into ./videos/ and tell me the file path.
