- user_agent записывается в профиль при первом запросе сессии, дальше игнорируется (#87) - переданные cookies заменяют cookies профиля (clear_cookies перед add_cookies) (#88) - без user_agent профилю генерируется отпечаток browserforge (Linux Chrome): UA с версией установленного Chrome, экран и devicePixelRatio; только нативная эмуляция, без JS (#89) - make fp-check: проверка, что отпечаток применяется и стабилен, и доля различий профилей Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
