+## Launch prompt
+
+```
+Brainstorm + write the Solution Design for Feature #29 — interactive track-changes
+review in the markdown preview: clean zero-annotation editor (left) + the rendered
+markdown preview (right) as the single review surface; annotations on/off toggle;
+changes-since-baseline painted green=human / blue=LLM / strikethrough=deleted; ✓/✗
+accept-reject of the LLM's changes ONLY, driven from inside the preview webview.
+Markdown-only product (F6 deprecated as a view; rename deferred). Mostly assembly
+of F3/F4/F6/F7/F9 + 3 new pieces. Per issue #29.

+finalize. Empty if none._
