"""AnimeciX kaynağı (minimal Python port)

Bu modül, AnimeciX API uçlarından arama ve bölüm/izleme verilerini çeker.
Mevcut `objects.Anime/Bolum/Video` yapısına dokunmamak için, yalnızca
harici arama/episode/watch listesi sağlar; indirme/oynatma yine yt-dlp/mpv ile.

Cloudflare koruması için cf_bypass modülü entegre edilmiştir.
