หมวดหมู่:หน้าที่ใช้โฟนอส

I don't have sufficient context to write an accurate overview. The context you've provided only indicates this is a "Wikimedia category" but doesn't explain what the Phonos extension is, what it does, or why pages using it would be categorized together. Without that information, I cannot write an accurate plain-language explanation without inventing facts.
