Panel behavior

The panel opens as a horizontal split to the right of the source surface. The tab shows the filename and a document icon; the file path appears as a breadcrumb at the top. Content is read-only with text selection enabled.

Markdown panels are saved and restored across sessions and re-read the file from disk on restore. A panel is not recreated if the file no longer exists at restore time.
