"""yesporn.vip — KVS engine direct stream extractor.

User bug-report 2026-05-27 (#1, scene 0d8ec317): "Yespornvip dalej nie działa".
Origin `tube:yespornvip` istniał w playback_sources ale brak wpisu w `_REGISTRY`
→ `try_extract()` zwracał None → mobile player no-source.

Detail page sceny linkuje do `/embed/<id>` w iframe. Embed page renderuje KVS
player z `flashvars`:
  - `video_url: 'function/0/https://yesporn.vip/get_file/7/<token>/.../<id>.mp4/?embed=true'`
    — **NIE używać.** Server `/get_file/7/` wymaga PHPSESSID + cookies z embed
    page (testowane 2026-05-29: 404 nawet z fresh tokenem, mobile-side cookies
    nie matchują VPS-side session). KVS kt_player.js loaduje to wewnątrz
    embed page gdzie cookies są dostępne.
  - `event_reporting2: 'https://yesporn.vip/get_file/1/<token>/.../<id>.mp4/'`
    — server `/get_file/1/` jest standalone, time-bound signed URL, **200 OK**
    direct fetch z headerami (UA + Referer). Bierzemy to.
  - `video_url_text: '480p'` — quality label.

Single quality (480p) z embed. CDN time-bound signed, mobile gra direct z phone
IP (zero VPS bandwidth).
