Subject: [PATCH] fix: switch Cusdis to iframe embed to avoid CORS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Replace <script src> approach with programmatic iframe creation
- No cross-origin script loading — avoids CORS blocks entirely
- Guard against missing container with null check
