seedance-ad-creative: cinematic product/brand ad clips

Turns a product description (or a product photo) into a commercial-style video clip: camera language, product framing, and brand tone become a Seedance 2.5 prompt, which this skill submits, polls, downloads, and reports the cost for.

This skill is a thin, scenario-specific layer over ofox-video-core. It owns the ad-creative prompt craft, the creative brief, recommended defaults, and the pre-generation cost estimate; ofox-video-core owns talking to the Ofox API correctly and safely (the OFOX_API_KEY handling, the no-resubmit rule, error-code mapping, download/verification). Read that skill's safety contract before using this one — it is not restated here.
