highlighted_hash grows a width budget - shorter than the key shows an ellipsis, shorter keys pad so lanes align - making it THE hash widget. The chat sender palette moves to theme.name_style as the app-wide node name colour rule; our own node is always the pure-white "you" style (the nodes table's self row now follows it).
