+    Generated from `#{source}`. The source Moon and original stand were not modified.
+
+    Three curved stems fork toward neighboring pads; each concave pad joins two branches.
+    The mesh is one connected, watertight, material-unassigned solid.
+    Dimensions: #{result.statistics["dimensions_mm"].map { |v| format("%.2f", v) }.join(" × ")} mm.
+
+    #{result.statistics["print_guidance"]}
+    Inspect the sliced layer preview before printing. Start with build-plate-only supports;
+    adjust local support painting beneath the cradles if automatic supports wrap around them.
+    The generator reports geometric overhangs, not a guarantee of a slicer's support layout.
+
+    The dish follows the conservative lunar sphere; terrain peaks may still limit actual contact.
+    See `statistics.json` for sizing, clearance, connectivity, and overhang measurements.
