What
Published documents lost their owner/date/status header block, which is now left to the artifact's own chrome, and the paragraph-style dropdown was replaced with a custom menu that previews each option in its own type style. Re-picking the style a block already has is now a no-op, which stops the block being rebuilt and a pinned comment thread being detached from it.
Details
- The menu supports Escape and arrow keys and restores focus to the toggle button when closed.
- The toolbar no longer fades: it sits on its own band with a border, and Save is a filled primary button.
- Typography was re-specified on a 28px baseline with a 34em line measure, plus a reader-only pretty text wrapping mode.
