Under the hood
Panes in Claude Code's terminal UI can now be highlighted with a distinct 'suggestion' top border
What
The Pane component used to draw boxed sections in Claude Code's terminal interface now accepts new lit and resize properties. When lit is set, the pane's top border is drawn in a distinct highlighted color instead of the normal dim border.
Why
This gives Claude Code a visual way to call attention to a specific pane, such as one being suggested to the user, without changing the rest of its styling.
