One Article, Multiple Languages

Core idea: each article is a translation group, and each language has its own independent title, slug, and real translated body text.

• URL: all languages have prefixes, such as /zh/article-slug, /en/article-slug
• AI: OpenAI-compatible interfaces are configurable (default: DeepSeek)
• Workflow: AI generates a draft → manual bilingual review → publish

Untranslated languages automatically fall back to the default language for display.
