# Naoki Urasawa Ideogram4 v1

LoRA (lokr) adapter trained on **Ideogram 4** (`ideogram-ai/ideogram-4-fp8`) for a **Naoki Urasawa style**.

## Prompt format

Ideogram 4 does **not** take a plain-text prompt. It expects a structured **JSON** prompt. This LoRA is activated by setting the style fields:

- `style_description.art_style`: `Naoki Urasawa style`
- `style_description.medium`: `manga_page`

Fill the rest of the JSON schema (`high_level_description`, `style_description.aesthetics/lighting/color_palette`, `compositional_deconstruction`) to describe the scene.

### Example JSON prompt

```json
{
  "high_level_description": "A humanoid robot stands on a rooftop overlooking a city skyline at night.",
  "style_description": {
    "aesthetics": "black_and_white",
