/**
|
|
* DefaultImageAdapter — handles the standard ComfyUI image output format.
|
|
*
|
|
* Most image-producing nodes (SaveImage, PreviewImage, color correction,
|
|
* blur, LayerStyle nodes, etc.) output in the canonical format:
|
|
* { images: [{ filename, subfolder, type }] }
|
|
*
|
|
* This adapter catches all of them with a single implementation.
|
|
* Priority 0 (lowest) so custom adapters can override for specific node types.
