  "body": "## Overview\n\n`@unifast/shiki` provides syntax highlighting powered by [Shiki](https://shiki.style/), supporting 200+ languages and a wide variety of themes. Unlike the built-in highlight plugin, Shiki runs as a HAST transform in JavaScript, replacing `<pre><code>` blocks with richly styled output.\n\nThe plugin automatically disables the built-in Rust highlighter to avoid double-processing.\n\n## Installation\n\n## Type Definitions\n\n### ShikiTransformerOptions\n\n| Property | Type | Default | Description |\n|----------|------|---------|-------------|\n| `themes` | `BundledTheme[]` | `[\"github-dark\"]` | Shiki themes to load |\n| `defaultTheme` | `BundledTheme` | First theme in `themes` | Default theme for rendering |\n| `langs` | `BundledLanguage[]` | `[]` | Languages to load.
