"""4k69.com — get_file stream extractor (platforma jak fullmovies/hdporngg).

Scene page (SSR za Cloudflare → curl_cffi) ma 3 get_file URL-e na www.4kporno.xxx
(`..._2160m.mp4` / `_720m` / `_480m`) — w JSON-LD contentUrl i w JS playera, NIE
w `<source>` tagach (dlatego nie _source_getfile, tylko skan całej strony).

Jak fpvcdn (fullmovies, ta sama rodzina `/get_file/8512/`): get_file binduje CDN
do IP fetchera, jest stateless i ważny ≥90s → oddajemy NIEZRESOLWOWANE z
mobile_direct_ok — telefon follow-uje 302 z własnym IP (cross-IP test 2026-06-10:
lokalny ISP 206 video/mp4). 2160p pomijamy (CDN time-out ~30s, jak fpvcdn).
