  "title": "小小守護隊 — 第一批美術概念稿",
  "startedAt": "2026-10-25T01:52:15Z",
  "method": "Built-in image_gen; five independent generation requests. AI-generated hand-painted-style concept sprites, not human hand-drawn art.",
  "status": "Web visual prototype; not integrated into Mindustry. Turret/drill moving parts are not separated. Grass seamlessness is unverified. Original examples are source layers, not full in-game composites.",
  "generationAttempts": 6,
  "grassRetryPrompt": "Create ONLY an empty seamless grass terrain texture tile for a top-down 2D cartoon game. The ENTIRE image must be flat grass from directly overhead, edge to edge, uniformly low contrast spring green and mint green. Soft hand-painted broad brush color patches and a few tiny grass strokes. ABSOLUTELY NO buildings, structures, machines, characters, objects, circles, platforms, icons, rocks, paths, shadows, foreground subject, text, borders or frame. This is an EMPTY BACKGROUND TEXTURE, not an illustration of a game object. Seamless repeating square tile, understated detail, opaque full bleed. Do not reuse any previous mechanical subjects.",
  "basePrompt": "Use case: stylized-concept. Asset type: standalone 2D RTS/tower-defense game sprite, original hand-painted cartoon style. Bright cheerful family-friendly rounded mechanical toy aesthetic, clean warm dark-teal outlines, soft painted shading, mint turquoise, butter yellow, coral orange accents. STRICT straight top-down orthographic camera, looking vertically down, no isometric perspective, no visible tall front facade, square footprint, centered complete object with 12% clear padding. Readable silhouette at 64px. No text, letters, numbers, watermark, ground tile or cast shadow outside footprint. ",
  "assets": [
    {"id":"core","prompt":"One cozy rounded square home-base core building, turquoise housing, cream central roof panel with tiny heart-shaped coral power light, four chunky golden corner bumpers, small leafy roof detail. Mechanical building not a character. Transparent background.","transparent":true,"original":"blocks/storage/core-shard.png"},
    {"id":"duo","prompt":"One friendly twin-barrel defensive turret, round mint mounting base, coral rim, two short cream-and-gold cannon tubes pointing straight UP in image, articulated head visually distinct from base, playful chunky proportions.

    {"id":"drill","prompt":"One adorable compact mining drill building, rounded-square butter-yellow chassis, mint corner feet, a clear central spiral drill head visible from above, coral motor and tiny turquoise vent. Transparent background.","transparent":true,"original":"blocks/drills/mechanical-drill.png"},
    {"id":"dagger","prompt":"One small friendly ground combat robot, two chunky rounded mint mechanical legs seen from above, cream oval body, coral shoulder guards, two small gold weapon tips pointing straight UP, toy-like nonhuman proportions, no humanoid face visible from overhead.

    {"id":"grass","prompt":"A single seamless flat top-down square grass terrain texture. Soft mint and spring-green hand-painted grass, gentle broad color patches, tiny sparse grass strokes, extremely subtle detail so buildings remain legible.
