Templates page is now a tree-only browser; editing happens on a dedicated TemplateEdit page. Drag-drop is replaced by context-menu Move-to-Folder. TreeView gains Bootstrap Icons (chevron + per-kind glyphs), ancestor guide lines, defined hover/selected/focus tokens, and Escape-dismisses-menu per the new Visual Design Guide (V1-V7) in Component-TreeView.md.
