     *   **Smart Grænse:** Definer en MB-grænse (standard 30 MB), hvor filer herunder altid hashes, mens større filer (f.eks. 65 GB) kun sammenlignes på størrelse for at spare tid (kan konfigureres).
 *   **Robust Bibliotekssøgning:** Finder automatisk dit bibliotek og har indbygget fallback (f.eks. fra "Delte dokumenter" til "Documents").
 *   **Resume Download:** Understøtter HTTP `Range` headers for genoptagelse af store filer.
-*   **Auto-Refresh af Downloads & Tokens:** Fornyer automatisk sessioner og links midt i processen.
-*   **Exponential Backoff:** Håndterer Microsoft Graph throttling (`429 Too Many Requests`) intelligent.
+*   **Auto-Refresh af Downloads & Tokens:** Fornyer automatisk sessioner og links midt i processen uden unødig ventetid (Optimized 401 handling).
+*   **Intelligent Fejlhåndtering:** Inkluderer retry-logik med exponential backoff og specialiseret håndtering af udløbne tokens (safe_graph_get).
