One file overlapped and git merged it cleanly: ChatRoomDetailScreen.kt, where mantra turned `parentChatRoomIds` into `parents` carrying each parent's room, and this branch added the "Add dialects from a list" button under the dialect list. Checked rather than assumed -- the merged file is mantra's version plus only this branch's additions. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
