Why: Approved redesign phase 4: process folds, long-reply folds, thinking blocks and context-observation fold move to the @ui Collapsible primitive (two-layer height+fade animation, delayed unmount, open-state memory); tool calls render as ToolBlock rows with running sweep and paired results; the live bar gains the ZCode worked-time line with sweep; input placeholder states the backend's honest busy semantics (serialized per conversation). Evidence: npx tsc -b clean; npm test -> 39 passed (details-guard included); npm run build succeeds; combined make test recorded in the Dev task card. Impact: Conversation.tsx replaces all <details> usage (guard-enforced); ProcessParts pairs tool_call with its trailing tool_result into ToolBlock; styles.css rewrites fold selectors for the Collapsible structure and adds message mount animation (mk-rise-in); no contract or API changes.
