 "body": "## The prompt, in order\n\n1. **Reference roles,** one line each, including what not to take from each image (keep the face, do not take the background).\n2. **One paragraph of full sentences,** never a comma list: the register first (candid, editorial, documentary), then the subject in a physical state doing one thing, the real place, where the camera stands, the light and where it comes from.\n3. **A capture line:** lens, aperture or depth, grain or none, the grade, the direction of the light.\n4. **Text** in quotes with its position. Otherwise signs, screens and packaging carry no letters.\n\n## What we measured (June to Sep 2026)\n\n- Early words weigh most: the register goes in the first sentence.\n- Positive descriptions beat bans; an exclusion works for what not to take from a reference and for an attribute of a named object.\n- The same prompt in another ratio drifts; give the approved image back as a reference.",
