Vimeo Locked-Embed Caption Extraction

Extract auto-generated captions/transcript from a privacy-locked (domain-restricted) Vimeo embed when the player refuses to play. Use when: (1) you need a transcript of a video interview/talk that's embedded as Vimeo on a third-party site (VC blog, conference page, paywalled article), (2) opening player.vimeo.com directly returns "video cannot be played here due to privacy settings" or "由于隐私设置，该视频无法在此处播放", (3) the host page publishes no transcript and yt-dlp / Whisper would be overkill. The player HTML leaks a signed captions.vimeo.com VTT URL even when playback is blocked — fetched with a correct Referer header.
