1// nx_imgsrc_probe.nx -- headless diagnosis: after the SHARED br_layout, does page.bsrc_off get the
2// <img src> for image boxes? Lays out a saved HTML file and prints every box that received a src.
3// If images have their src here, the bug is downstream (GUI fetch/decode/blit); if not, br_layout's
4// positional element->box src mapping is dropping them (a shared fix).
