-### 🎨 Shiki Compatibility Notice
-
-Syntax highlighting depends on `rehype-pretty-code`'s deprecated `getHighlighter` API from `shiki@legacy`.
-
-**Key Points**:
-
-- **Affected File:** `src/components/mdx-preview.tsx`
-- **Dependency Chain:** `rehype-pretty-code` → `shiki@legacy`
-- **Version Constraints**:
-
-  ```sh
-  "shiki": "<=2.5.0"
-  "@shikijs/monaco": "<=2.5.0"
-  ```
-
-**Maintenance Note**:  
-While `shiki@3.0.0+` introduces modern APIs (`createHighlighter`/`getSingletonHighlighter`), upgrading requires `rehype-pretty-code` updates. Track progress [here](https://github.com/atomiks/rehype-pretty-code).
