   durations, as in TypeScript. With one part, the `E.6a/transcript` cells match.
 - The open body is the Markdown widget with every syntax style in `text.muted`. P-APP has no scenario with an
   open block yet, so how its cells differ from the code view is not measured.
-- `session.toggle.thinking` switches the mode for the open session view only.
 
-Reason: the Rust `Code` widget has no conceal, so the Markdown widget renders the body. The `cli.json` write
-can use `dialogs::settings::update` now; the toggle belongs to E.6a's transcript layer and moves to it with the
-next change there.
