     66= 1.1.0 =

     68* Fix: badge wrapper no longer breaks <picture> elements, paragraphs or left/right/center alignment.
     69* Fix: the "AI Generated" checkbox is shown only for images.
     70* Security: saving the checkbox now relies only on the core attachment save flow with a capability check.
