## Format Notes
|
|
|
|
- H1 `#` for background name
|
|
- H2 `##` for each section, must include these 5 sections:
|
|
- `## Scene Description` — itemized list: environment type, terrain/space, palette/atmosphere, key elements, weather/time
|
|
- `## Scene List` — which scenes this background appears in (extracted from script.md)
|
|
- `## Image Settings` — contains three sub-fields:
|
|
- `Prompt:` — English, combining scene description with art style keywords, must include `no people`
|
|
- `Model:` — image generation model name
|
|
- `Reference:` — art style reference image path (relative to theme directory)
|
|
- `## Candidates` — all generated candidate image paths (relative to background directory), with model and composition notes
|
|
- `## Selected` — final selected image path (chosen by user in preview page)
|
|
- Images stored in the background's directory (candidate_*.jpg, selected.jpg)
|
|
- Before user selection, `## Selected` section is left empty
|
|
- **Aspect ratio: always 16:9 widescreen** (`aspect_ratio: "16:9"`) to showcase full scene
