### Phase 4: Components + Variables ✅

Components, instances, overrides, variables, collections, modes, image export.

- Always-visible purple component/instance labels with diamond icon
- Opaque container hit testing (click selects component, double-click enters)
- Right-click context menu with clipboard, z-order, grouping, component, visibility, lock, move-to-page actions
- Z-order manipulation (] bring to front, [ send to back)
- Toggle visibility (⇧⌘H) and lock (⇧⌘L)
