"""galaxyporn.net — browse scraper (WordPress retrotube). Dodany 2026-07-26.

Ripy paysite ze studiami (BrazzersExxtra, EvilAngel, NubilesPorn, RealityKings,
MYLF, BlackedRaw…). Ocena: orphan-risk LOW z twardym pomiarem — 92% performerów
z próbki 75 ma już u nas ref tpdb/stashdb, 79% tytułów matchuje istniejące sceny.

Listing `/page/N/`, 21 scen/stronę, ~1180 stron, paginacja zdrowa (overlap p1/p2 = 0).

Metadane:
  - obsada: `<div id="video-actors">` — czysta, BEZ pollution (na całej stronie sceny
    są dokładnie te 2-3 linki `/actor/`, nie ma sekcji Related z obcymi performerami)
  - studio + data: prefiks tytułu `Studio YY MM DD Performer – Title` albo `[Studio]`
  - tagi: `<div class="tags-list">` (wycinamy slug studia, żeby nie robić tag=studio)
  - thumbnail: `data-main-thumb` / og:image

**Duration — uwaga, nie ma go w HTML.** Ani listing, ani detail, ani JSON-LD, ani
payload playera nie niosą długości. NULL duration jest GROŹNY: `/scenes` filtruje
`duration_sec >= min_duration_sec`, a NULL w SQL odpada z wyniku, więc sceny byłyby
NIEWIDOCZNE w apce mimo "new: N, errors: 0" (dokładnie incydent porntrex, 6479 scen).
Dlatego liczymy ją z `thumbnail.vtt` playera (ostatni cue), 1 dodatkowy request na
scenę po odpytaniu API seekplayer. Wartość jest ~1 interwał miniatur krótsza od
realnej (2226 s vs ~2276 s na próbce, ~2%) — akceptowalne, bo alternatywą jest brak.

Playback: iframe `#hash` rodziny seekplayer (galaxy.upns.online / galaxy.4meplayer.pro /
sport.seekplays.com / news.upns.pro) → extractor `galaxyporncom` → istniejący
`seekplayer_engine` (ten sam AES key/IV). HLS wymaga Referera → `/proxy/hls`.
