"""porndoe.com — latest-vids browse scraper.

Dołączony 2026-05-21 (theporndude audit). Jedyny verified high-value candidate
z 172 tube'ów na theporndude.com/top-porn-tube-sites + /full-porn-movies-sites.

Czemu wart: każda scena ma kompletny **JSON-LD VideoObject** schema:
  - name (title), description, uploadDate (ISO timestamp), duration (ISO 8601)
  - producer + publisher → named studio z `/channel-profile/<slug>` URL
  - actor[] → named performers z `/pornstars-profile/<slug>` URL
  - thumbnailUrl (CDN p.cdnc.porndoe.com)

To wystarczy do composite fuzzy match w resolverze (studio + performer Jaccard +
date proximity + title token-set + duration). Phash hit-rate niski (porndoe robi
własne crop-thumbnaile 390x219, nie hot-linkuje studio art) — ale rich metadata
nadrabia, jak pornxp/porn00.

URL patterns:
  - Listing: `/videos/most-recent?page=N` (page 1 = newest, ~31 scen/page)
  - Scene:   `/watch/<id>` gdzie id = `pd` + 10 alfanum (stable)
  - Studio:  `/channel-profile/<slug>`
  - Performer: `/pornstars-profile/<slug>`
  - Tags/categories: `/categories/<slug>`

Playback: stream URL NIE jest inline w SSR HTML — player JS init dopiero po user
"Play" click. Dajemy playback_source z page_url + origin `tube:porndoecom`;
extractor w `_REGISTRY` mapuje na `_vps_blocked_fallback.extract` → mobile WebView
INJECTED_JS scrapuje `<video>.src` po phone IP (0 VPS bandwidth, zgodne z
pre-public bandwidth/anonimowość priorytet).
