56-64: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExercise the delayed DOM insertion path in this test.
This test calls
translateTextdirectly. It does not start the browser integration, attach aMutationObserver, insert a node after Chinese mode is active, or verify restoration for that node. It can pass even when delayed shared-header translation is broken. Add a DOM-level regression test for the observer path.🤖 Prompt for AI Agents

In `@site/home-i18n.js`:
- Line 80: Update the translation lookup in the surrounding function to check
whether middle is an own property of zh before using its value, preserving
middle as the fallback for missing translations and avoiding inherited
Object.prototype properties.
- Line 86: Update the document language assignment to use the normalized active
language value rather than the raw lang input, preserving the fallback to
English for unsupported values. Modify the assignment near the active language
calculation.
