<summary>Features</summary>

* **Flatten PDF Feature:** New checkbox in the Signature Order module. This feature improves compatibility for documents by removing form fields (flattening), preventing errors during signing. Please note: Documents already signed with QES must not be flattened, as this would invalidate all signature by altering the document.
* **Signing only on auth device security measure:** Only devices authenticated via PassKey or FaceAuth are now permitted to initiate signing (by clicking the "Sign" button):

  * Mobile Flow: Remains unchanged.
  * Desktop Flow: Users will see a the QR code displayed on the desktop when signing (same as during the scanning process).

  Please note that the "PDF Preview" step is still available on the desktop.
* **Randomization security measure:** The liveness steps (zoom, head turn, and smile) will now appear in a randomized order for each process. Each step will still occur only once per session.
