 ### 3. Key Implementation Details
 
 #### ✅ Isolated Task Processing
+
 - Each `SeriesLoadingTask` contains data for **exactly one anime**
 - Tasks are processed sequentially from the queue
 - No cross-contamination between anime
 
 #### ✅ Targeted NFO Creation
+
 - `NFOService.create_tvshow_nfo()` receives parameters for **one anime only**
 - Downloads poster, logo, fanart to **that anime's folder only**
 - TMDB API calls are made for **that specific anime's name/year**
 
 #### ✅ No Global Scanning
+
 - `SerieList.load_series()` only **checks** for existing files
 - It does **not** download or create any new files
 - Used only for initial library scanning, not during anime add
 
 #### ✅ Isolated Episode Scanning
+
 - `_load_episodes()` uses `_find_series_directory()` and `_scan_series_episodes()`
 - Scans **only the specific anime's directory**, not the entire library
 - No impact on other anime
