 Fenced code uses [HighlighterSwift](https://github.com/smittytone/HighlighterSwift) (Highlight.js) for language-aware token colors. Add a language after the opening backticks or tildes, for example `py`, `python`, `swift`, `js`, or `json`. Unlabeled fences use automatic detection; unknown languages remain plain monospace. Highlighting runs entirely offline.
 
+Embedded images display with 8-point rounded corners. Rounding only clips their rendering in Notes; saving and copying retain the original image data.
+
 Notes autosave locally as RTFD packages, including embedded images, under `~/Library/Application Support/Conjure/Notes`. No account, network access, or cloud sync is involved. Save failures appear below the editor and prevent switching, closing, or quitting until saving succeeds, preserving the unsaved buffer. The Close button and Command-W dismiss Conjure, including any open popup; leaving Notes or switching destinations removes its popup completely and restores the launcher’s original dimensions.
