New features

- Edit your lessons by chatting with the AI Assistant: Ask the AI Assistant to change a card or lesson in plain language, then review and accept its edits. Now available to everyone.

Improvements

- Sharper AI-generated and edited images: AI image generation and editing now run on an upgraded model, producing higher-quality, more consistent visuals for your courses.

- A smoother, clearer AI Assistant: The AI Assistant now shows richly formatted replies, a steady working indicator, and a Stop button to cancel a request at any time.

Bug fixes

- Course preview narration no longer loops: Full-lesson narration in course preview now plays through once and stops, instead of restarting from the beginning when the audio finishes.
