## Field Reference

| Field | Type | Default | Description |

| `watermark.content` | string | "" | Watermark text (@username or custom) |
| `watermark.position` | enum | bottom-right | Position on image |
| `preferred_style.name` | string | null | Style name or null |

| `default_output_dir` | enum | null | Output directory preference (null = ask each time) |
| `preferred_image_backend` | string | `auto` | Image backend selection. `auto` = prefer runtime-native tool, fall back to the only installed backend, ask if multiple non-native are present. `ask` = always confirm on every run. `<backend-id>` (e.g., `codex-imagegen`, `baoyu-image-gen`, `image_generate`) = pin this backend when available; fall back to `auto` when it isn't.
