web-video-presentation 是做什么的？
Convert an article or spoken script into a click-driven 16:9 web presentation that "looks like a video," with optional voice-over audio synthesis. Workflow: original article → one-shot generation of script + outline dev plan → user one-pass alignment of 5 items (script / outline / theme / assets / dev mode) → web development (chapter-by-chapter / sequential / parallel) → optional audio synthesis (provider-agnostic: built-in MiniMax mmx-cli + OpenAI TTS, swappable with ElevenLabs / edge-tts / Azure / custom TTS). The outline only plans pacing and information density — not animations — animations are designed ad-hoc during chapter development following PRINCIPLES + ANTI-AI guidelines. Each click advances one beat of the script; each step occupies the full screen; the progress bar is hidden by default and appears only on hover. Use cases: create a video-like web page (dynamic PPT but not like PPT), turn a script/article into an interactive narration, record screen tutorials for Bilibili / YouTube / WeChat Channels, build cinematic product or talk demos. This skill encapsulates a design methodology + collaboration workflow — it is not tied to any specific style / font / color — so it can be reused across any theme and aesthetic.
