After the delimiter fix, the live cheunart fetch 302'd to /cheunart/verify_
subscriber even with valid .adult cookies (confirmed present: _personalization_id
+ _subscribestar_session on .subscribestar.adult, logged in). Walking gallery-dl's
ENTIRE flow — including the base Extractor._init_session I'd not read — the
divergence is the HTTP request profile, not the cookies or parser.
gallery-dl's default (cookies-only) mode sends, on EVERY request including the
first creator-page GET: a Firefox UA, Accept: */*, Accept-Language, and a same-
site Referer (root/), with NO X-Requested-With anywhere (the load-more endpoint
is a plain GET parsed as JSON). Our Chrome UA + missing Referer + XHR toggling
looked unlike a browser → SubscribeStar gated the adult-creator page.
Make our SubscribeStar session identical: Firefox UA + Accept */* + Accept-
Language via make_session extra_headers; stamp Referer=<base>/ per walk; drop the
per-request XHR headers (both feed and load-more now use the shared profile).
Test updated to assert the gallery-dl-parity profile instead of the old
navigation-vs-XHR split.
