How It Works

1. User selects image file (.img or .img.xz)
2. User selects console (Original / Clone) and panel
3. User selects target SD card
4. App writes image to SD card (with xz decompression if needed)
5. App opens FAT32 BOOT partition directly on the block device (no OS mount)
6. Copies selected panel DTB as kernel.dtb
7. Writes panel.txt, panel-confirmed, and variant
8. SD card is ready. Insert in R36S and power on.
