Fixed ad cards rendering inside the user's message bubble on claude.ai instead of below it. Claude updated their page structure, which broke the marker the extension used to place the card; the extension now recognizes multiple known page layouts so it keeps working even if Claude changes its structure again.

What's changed
-Fewer repeated sponsored cards in a single session.
-Security hardening: the sponsored card no longer builds any of its content via HTML string interpolation.
-Fixed ad injection on ChatGPT's logged-out composer.
