…rap in fenced code block On paste into a CodeMirror markdown editor, detectSmartPaste() checks for a strong structural signal (MIME type or unambiguous parse) and, when confident, inserts the content as a fenced code block with the detected language tag. JSON is pretty-printed. Prose-like text always falls through to normal paste so false positives cannot wrap ordinary text in code fences. The paste is a single dispatch transaction, so Yjs undo reverses it in one Cmd+Z. Closes #122 https://claude.ai/code/session_01QimxGbNH9tVirc5fJDPcGA

Closes #122
What
Adds smart paste detection to the CodeMirror markdown note editor. When pasting content with a strong structural signal, it's automatically inserted as a fenced code block with the detected language tag.
Detection logic
Two layers, cheapest first:
image/svg+xml→svg,application/json→jsontext/plain:<svgand closes with</svg>→svgjson(pretty-printed)<!DOCTYPE html>or<html→htmlUncertain content always falls through to normal paste — bias is hard toward doing nothing so mis-fires can't wrap prose in code fences.
Undo
The formatted insert is a single CodeMirror dispatch transaction, captured by the Yjs UndoManager as one operation. One Cmd+Z reverses it.
