@wdkns/bilibili-render-pdf

Generate a professional, detailed, figure-rich LaTeX course note and final PDF from a Bilibili lecture, tutorial, or technical talk. Use when the user provides a Bilibili URL (BV number) and wants structured Chinese teaching notes that combine the video's title, chapters, diagrams, formulas, code, subtitle explanations, the original video cover on the front page, and a final synthesis chapter, with key frames extracted from the highest usable video resolution and inserted as figures, and where the final deliverable must include a rendered PDF. Falls back to Whisper speech-to-text when no CC subtitles are available.
