      "acceptance": ["All four locations feel like parts of one Minecraft world", "Guesthouse and crossing preserve their different chapter roles", "Quarry access and the first underground return path are readable", "The Shallows retain their pale rock, roots, water, and connection to the surface", "Lighting supports the established warm-refuge and rich-landscape target without inventing required gameplay effects", "No additional planet, new cast, industrial complex, or deep-realm requirement is introduced"],
      "future_prompt": "Create a compact four-panel SUBSTELLAR concept board in the established Minecraft block scale and the warm sunlight, rich blue water, readable natural terrain, and maintained refuge mood of the existing Overworld and Shallows references. Show four related places: GUESTHOUSE, OLD CROSSING, QUARRY, COPPERWASH CHANNELS. Show a modest guesthouse restoration, an authored timber-and-stone crossing with an understandable route, a worked quarry with a small manual hoist and a marked underground entrance, and a pale rooted Shallows passage with copper-stained stone, a shallow stream, one local landmark, and warm return lamps. Preserve ordinary early materials and player scale. Landscape and useful structures dominate. This is one concept board of possible views, not a precise geography map, final block layout, or promised lighting implementation. Four simple panel labels only. Do not invent named characters, giant settlements, futuristic machines, space hardware, or inaccessible required resources."

      "future_prompt": "Create one compact SUBSTELLAR early-workshop concept board in Minecraft block geometry. Use timber, ordinary stone, brick or refractory hearth material, iron hardware, copper, and restrained bronze details. Show a coherent work area with the Carpenter and repair bench, a small Alloy hearth, and a nearby hand-operated Hoist and lift installation serving a fixed quarry landing. Make the path from raw metal stock to finished bronze fittings to an improved cargo-handling service understandable. Include small supporting views of idle, active, and visibly blocked states using pose, part movement, load position, and simple physical indicators. Match the existing warm, useful Old Valley environment. Maintain player scale and accessible working faces. Broad, legible concept detail is enough. Use only short subject or state labels. Do not add advanced electronic factories, complex fluid chemistry, extra technology tiers, free-moving cranes, spacecraft, or final manufacturing dimensions."
