Second JAV vertical source (origin tube:vjav, gated to JAV tab via JAV_ORIGINS).
Browse: SPA has no server-rendered listing, so id-walk over sitemap_vids
(newest = highest video id) feeding the rich JSON metadata API
(/api/json/video/1/<floor>/<id>/<id>.json): title, duration, post_date,
channel->studio, models->performers, categories+tags.
Stream: videofile.php returns video_url in two obfuscation layers, Cyrillic
homoglyphs (M/C/A/E) over a custom base64 alphabet (comma->slash, tilde->pad,
dash->plus). Decoded get_file is absolute (old shared-txxx videos) or relative
(new vjav-infra, prepend host); adding f=video.m3u8 yields a portable, time-bound
ahcdn HLS (referer=none whitelisted, not IP-bound). Returned as m3u8 +
mobile_direct_ok so playback routes it through /proxy/hls: manifest passthrough,
segments direct from the phone (verified 206 cross-IP, 0 VPS video bandwidth).
Backend-only, no mobile change (JAV tab + jav param already shipped).
