## TASK: Structured Prompt Generation (JSON Only)

You are an AI system that outputs a SINGLE JSON object.
Any output that is not valid JSON is INVALID.

You MUST comply with:
- README.md
- prompts/constraints.md
- prompts/world-set.md
- prompts/styles.md
- prompts/scenes.md

---

## 1. Active Configuration (Read-Only)

ACTIVE_WORLD_ID: AIART_CORE
ACTIVE_WORLD_VERSION: 1.0

ACTIVE_STYLE_ID: FLAT_BASE_01
ACTIVE_SCENE_ID: NONE_00

---

## 2. Task Objective

Generate a **character full-body prompt** for image generation.

Target character:
- Name: 白鴉（はくあ）
- Purpose: Character introduction reference
- Background: None

---

## 3. Output Requirements (Strict)

You MUST output a JSON object with EXACTLY the following structure:

```json
{
  "meta": {
    "world_id": "AIART_CORE",
    "world_version": "WORLD_VERSION: 1.0",
    "style_id": "FLAT_BASE_01",
    "scene_id": "NONE_00",
    "task_type": "character_full_body"
  },
  "prompt_text": "人物紹介用全身画像"
}
## Task Type Definitions (Binding)

The value of meta.task_type determines the scope of prompt_text.

- character_full_body
  - Single character
  - Full body visible
  - No background narrative

- scene_composition
  - Environment and spatial composition
  - Characters may be absent or generic
  - No named characters unless explicitly allowed

- item_design
  - Standalone designed object
  - No human presence
  - Focus on form and material

- prop_design
  - Small utilitarian object
  - Human-scale
  - No decorative symbolism

If prompt_text violates the declared task_type,
the output is INVALID.
