  "prompt": "Edit this historical photograph for a clearly labeled educational demonstration of generative grain reduction. Preserve exact framing, every fire ribbon's position, the moving boat's blur, horizon silhouette, dark blue to cyan sky gradient and orange-red earth. Reduce visible fine grain modestly, especially sky; articulate existing earth subtly without inventing rocks, branches, foliage or changing composition. No sharpening the moving boat. No new objects or text. Preserve the long-exposure photographic character; do not make a new scene. Return the same full image framing. This is a teaching candidate, not a replacement original.",
  "correction_prompt": "Create a corrected teaching variant based on image 1, the original scan overview. Image 2 is the first generative candidate to critique, not the base. Its bottom earth has been changed and some flame details became simpler. Return to original geometry and original grain/detail in earth and flames. Change ONLY the flat upper sky above the distant tree line: subtly reduce grain there, keep the exact blue/cyan gradient, no added objects. Keep boat motion blur. Preserve all flame trails, soil and reflections as faithfully as possible to image 1. No invented rocks or foliage. Same full framing and aspect ratio as image 1. This is a new candidate, not an assertion of historical restoration.",
