  "concept": "Hollowheart Mason: a patient crystal-joint tuner shaped like a walking carved portal, with smaller luminous voids nested inside its chest.",
  "silhouette": "A squat angular open-frame torso, tiny chisel hood, one oversized faceted repair shoulder and broad planted feet; the chest opening stays legible from front and rear.",
  "details": "Bold basalt planes, pale crystalline limb blocks, a low stepped or forked crest, a patched violet shoulder and a square-ended tuning mallet; all matte, visibly faceted and readable at game scale.",
  "value": "At idle the mason listens with its tile and mallet lowered; at full activity it lifts the tile beneath its chest, taps it deliberately and pauses as light travels inward through the nested frames.",
  "animation": "Travel speed controls a planted alternating gait and restrained arm counter-swing. Activity independently raises the tile and taps it with the mallet, while idle listening and night glow continue.",
  "variation": "Independently combine pale ivory, lilac or celadon ceramic with violet, ochre or teal repairs and cyan, lavender or mint light; square or diamond nested chest frames, optional broad shoulder fin, stepped/forked/plain crest, hood profile, patches, mallet profile and body proportions. Preserve the hollow portal and civic tuning role.",
  "colors": "Obsidian #14121E and shadow violet #30233F form the torso; crystalline white #E9EDF7 defines limbs and cut edges; violet #63369A marks repairs and the tuning tile; cyan #53E8F4 lights the voids; gold #D8B96E is confined to small functional connections."
