Flashing

Key notes: This board ships pre-flashed with Dasharo and Heads from NovaCustom/Nitrokey — external flashing is not required for normal operation. The Dasharo external-flashing instructions cover both initial deployment and unbricking/recovery — see the Dasharo NovaCustom initial deployment and Dasharo NovaCustom recovery documentation.
