 ### V7 — Worked Example: `/design/templates`
 
-**Page model**: the templates page is a **tree browser only**. Selecting a template in the tree navigates to a dedicated edit page (`/design/templates/{id}`); creating a template navigates to `/design/templates/create`. No split-pane editor. Reorganization (move folder, move template) happens exclusively through the **right-click context menu** with modal dialog pickers — there is no drag-and-drop on this page.

+**Template tree search (M9/T22):** A search box above the tree is wired to `TemplateFolderTree.Filter`. Typing a term dims non-matching nodes (case-insensitive substring against folder/template name) while preserving tree shape and expansion state.

+**Folder sibling reorder (M9/T23):** The folder context menu exposes **Move up** / **Move down** items that invoke `ReorderTemplateFolderCommand` to swap `SortOrder` values for adjacent siblings. Root-level folders also have a context menu (previously only nested folders did). Drag-drop reorganization is **not implemented** — it is permanently deferred; the menu is the intended interaction model.
