Aoede can now create and edit notes as first-class documents, then switch the same note into the regular reader for text-to-speech and study capture. Notes live in their own library section, and selecting text in the editor can feed the same card-making flow used by books.
The awkward part was preserving everything attached to text after the text changes. On save, Aoede re-anchors cards, bookmarks, capture marks, and the previous reading position against the edited sentences. When a match cannot be found, it surfaces the orphan or falls back explicitly instead of silently pointing a card at the wrong passage.
