+## [Unreleased]
+
+### Changed
+
+- A chat's colour no longer tints the chat background (pane, message field, agent bubbles, top bar
+  fill); it still marks the top bar line, the list entry, the badge and your own bubbles.
+
+### Fixed
+
+- **Claude Code can ask questions again**: its `AskUserQuestion` was always rejected; now the question
+  appears as a question card in the chat (single and multiple choice) and the answers go back to it.
