Document structure: Document (root) → Pages (CANVAS) → Nodes.
Each page has its own viewport (pan/zoom) and background color.
- CANVAS node type for pages
- SceneGraph: addPage(), getPages(), getAbsolutePosition stops at CANVAS
- Store: currentPageId, switchPage(), addPage(), deletePage(), renamePage()
- All operations (create, select, paste, hit test, render) scoped to current page
- Per-page viewport state saved/restored on page switch
- Pages list in LayersPanel with add/switch/double-click rename
- .fig import creates proper pages from DOCUMENT→CANVAS hierarchy
- Renderer takes pageId to render correct page's children
- Unit test for pages, updated E2E tests for page-scoped graph
When nothing is selected, the right panel shows Page section with
a color picker for the canvas background (like Figma). The page
color is stored in reactive state and passed to the renderer.
- PropertiesPanel.vue: 513 → 67 lines (composition only)
- Extracted: PositionSection, LayoutSection, AppearanceSection,
FillSection, StrokeSection, TypographySection
- Shared useNodeProps() composable for update/commit logic
- Typography panel: font family picker with search (queryLocalFonts),
weight select, font size, line height, letter spacing, text alignment
- Font picker shows each family in its own typeface
- Loads selected font into both CanvasKit and browser on pick
