The entirety of the entirety of https://duckduckgo.com/ is unthemed. ### Relevant screenshots <img width="1714" height="1017" alt="Image" src="https://github.com/user-attachments/assets/4169c36f-3023-40fd-a977-a23609bc7a8b" /> <img width="796" height="107" alt="Image" src="https://github.com/user-attachments/assets/71d0fbbf-5073-47dc-9ad2-29b358167f63" /> ### Browser version(s) this issue occurs on Zen 1.20b [Build ID: 20260524090131] ### Stylus extension version Stylus 2.3.24 ### Installed version of the userstyle 2026.03.18 ### Any additional comments? _No response_
