/**
|
||||
* Unified client for Imajin image generation
|
||||
*
|
||||
* Primary usage - call the main orchestrator service:
|
||||
* ```ts
|
||||
* import { ImajinClient } from '@lilith/imajin-client';
|
||||
*
|
||||
* const client = new ImajinClient('http://localhost:8080');
|
||||
* const result = await client.generate({
|
||||
* category: 'escort',
|
||||
* city: 'reykjavik',
|
||||
* role: 'hero',
|
||||
* });
|
||||
* ```
|
||||
*
|
||||
* Advanced usage - direct access to individual services:
|
||||
* ```ts
|
||||
* import { PromptClient, DiffusionClient, ProcessingClient } from '@lilith/imajin-client';
|
||||
*
|
||||
* const promptClient = new PromptClient.ImagegenAssistantClient({ baseUrl: '...' });
|
||||
* const diffusionClient = new DiffusionClient.ImageGenerationClient({ ... });
|
||||
* const processingClient = ProcessingClient.createLocalClient();
|
||||
* ```
