LayerTree SDK components:
- LayerTreeRoot — tree data from editor graph, expand/collapse with
auto-expand on selection, scroll-into-view, scope sync
- LayerTreeItem — per-node slot with isSelected, padLeft, select,
toggleExpand, toggleVisibility, toggleLock, rename
App LayerTree.vue now composes LayerTreeRoot + LayerTreeItem + TreeRoot/
TreeItem from Reka UI. Deleted LayerRow.vue — its logic is in the SDK.
EditorMenu SDK component:
- EditorMenuRoot — selection-aware state (hasSelection, isInstance,
isComponent, isGroup, canCreateComponentSet, otherPages, visibility,
lock) + copyAsText/SVG/JSX via slots
App CanvasMenu.vue now composes EditorMenuRoot — pure template with
Reka UI ContextMenu + Tailwind styling, zero business logic.
Removed useSelectionState composable — EditorMenuRoot replaces it.
