无脸解说视频：turn arbitrary text — an article, notes, a topic, a brief — into a faceless explainer video, up to ~3 min (sweet spot 30-90s), where every visual is invented (typography, abstract graphics, diagrams, data-viz) rather than captured. There is no URL, no website capture, and no real assets. Use this skill for topic explainers, concept breakdowns, how-tos, listicles, and narrative explainers. Do not use it for a product launch/promo (use /product-launch-video), a tour of a real website (use /website-to-video), a GitHub PR (use /pr-to-video), captions on existing footage (use /embedded-captions), or a short unnarrated motion graphic (use /motion-graphics). If the intent is unclear, route through /hyperframes first.
