2. Reference motherboard photo

The original hardware photograph is retained without retouching. Its CPU protective covers already carry the English warning “SAVE AND RESTORE COVER IF PROCESSOR IS REMOVED,” alongside the corresponding factory Chinese line. This bilingual physical marking is preserved to avoid altering the hardware reference.
