Split the 12dp draggable divider into two 6dp halves: left half takes surfaceContainer (matching the conversation list pane's fill), right half takes surface (matching the chat pane's fill). The divider now reads as the shared edge between the two panes instead of a solid contrasting stripe cutting down the middle. https://claude.ai/code/session_01NufduPfZvYQVYwLkbCjCUo
