Backend Services

ConfigService

Handles reading and writing of API key and model configuration. API keys are masked when returned to the frontend.

PexelsService

Calls the Pexels API to search for high-quality royalty-free images. Supports keyword search and image download (10 MB limit).

WordService

Pure Go implementation of OOXML .docx file generation (ZIP-based format). Built-in styles with Microsoft YaHei font, heading layout, and body text styling.

CreatorService

Orchestration service that chains the full pipeline: AI generation → image search → image download → Word generation.
