Downloads balance-firmware.bin from Gitea release URL to inactive OTA partition, streams SHA256 verification via mbedTLS, sets boot partition and reboots. Auto-rollback via CONFIG_BOOTLOADER_APP_ROLLBACK_ENABLE if ota_self_health_check() not called within 30 s of boot. Progress 0-100% in g_ota_self_progress for display task.
