"""HQPornerBrowseScraper — latest-vids browse dla hqporner.com.

Dlaczego: hqporner był TYLKO w `ALL_DIRECT_SCRAPERS` (search po nazwisku performera),
więc nowe sceny wchodziły wyłącznie wtedy, gdy worker akurat szukał pasującego
performera. Efekt: 0 świeżych scen w 7 dni (audit 2026-07-26, user: "nie widzę nowych
scen z hqporner"), mimo że tube publikuje codziennie. Browse dokłada ścieżkę
niezależną od stanu performerów.

Listing: `https://hqporner.com/` (page 1 = newest), kolejne `?p=N`, ~46-50 scen/stronę.
Detail (`/hdporn/<id>-<slug>.html`) ma komplet metadanych:
  - tytuł        → `<title>` (Title Case; `<h1>` jest lowercase, więc gorszy),
  - długość      → meta description "Video duration is 46min 58sec",
  - performerki  → `<a href="/actress/<slug>">Display Name</a>` (display, nie slug),
  - tagi         → `/category/<slug>`,
  - miniaturka   → `fastporndelivery.hqporner.com/imgs/.../_main.jpg`.

`external_id` MUSI być identyczny jak w `HQPornerScraper` (search): `hqpornercom:<url>`.
Inaczej ta sama scena z obu ścieżek zrobiłaby się dwoma wpisami.

Miniaturki fastporndelivery wymagają Referera (bez niego 403) — backend i tak owija je
w `/proxy/img/`, a phash liczymy z jawnym refererem.
