Conversation
The diagram's copy button opens a menu like download's: Image (.png) puts the same PNG export on the clipboard, and Mermaid source copies the code. Each confirms with a toast.

Before: the copy button on a Mermaid block could only copy the diagram's source code.
After: the copy button opens a menu like the download one, with Image (.png) and Mermaid source. A toast confirms each copy.
How:
Diagram.tsxswaps theCopyButtonfor a dropdown. The image option reuses the PNG export from #8 and writes it withnavigator.clipboard.write, handingClipboardItemthe pending PNG promise so Safari still treats the write as part of the click. Failures show an error toast.Checked with
pnpm checkand in the dev server with Playwright: the image option puts a 1783×368image/pngon the clipboard, and the source option copies the Mermaid code.🤖 Generated with Claude Code
