Lane R1b — one file fails, the other five still land

Real create-listing photo uploader, headless Chromium. A 6-photo batch where 04-FAIL-bedroom.jpg fails mid-batch: the other 5 upload, stay in pick order, and the host is told exactly which one failed.

Desktop: 5 of 6 photos landed in order, failure message names 04-FAIL-bedroom.jpg — Desktop · 1280px

Mobile: 5 of 6 photos landed in order, failure message names 04-FAIL-bedroom.jpg — Mobile · 390px

Grid order is 01, 02, 03, 05, 06 — the failed slot 04 is dropped, not the whole batch. Message: “Added 5 of 6. Couldn't add this photo: 04-FAIL-bedroom.jpg. Re-add it to try again.”
