-### Tool button specs
-- Each button: 32×32px, class `toolbelt_button--topLevelButtonNew`
-- Flyout chevrons: 16×32px, class `tool_group--flyoutChevron`
-- Tool+chevron combined: 49×32px (32 icon + 16 chevron + 1px gap)
-- All buttons are `<button>` with `aria-label`

-
-Layer row class: `object_row--row--RUzis object_row--topLevel--SXq9o`
-Has `aria-label` on icons: Rectangle, Frame, Auto layout, Section, Instance
-
-## Right Panel (241px)
-
-### Header (above scroll, 240×48)
-- Tab strip: **Design** | **Prototype** (tabs__tabButton)
-- Zoom button: "100%" (60×24), clickable
-
-### Properties Sections (with a Rectangle selected)
-Panel scroll area: 240×820, class `properties_panel--scrollContainer`
-
-| y offset | Section | Content |
-|----------|---------|---------|
-| 0 | **Node header** | Type "Rectangle" + "Use as mask" toggle |
-| 49 | **Position** | Section label |
-| 89 | Alignment | 9-grid alignment buttons |
-| 121 | Position X/Y | Two number inputs (88px each) |
-| 153 | Rotation | Number input |
-| 198 | **Layout** | Section with "Dimensions" subsection |
-| 238 | Dimensions W/H | Two number inputs + lock aspect ratio |
-| 283 | **Appearance** | "Hide" toggle |
-| 368 | **Fill** | Color swatch + opacity input + visibility toggle |
-| 453 | **Stroke** | Section (collapsed when empty) |
-| 494 | **Effects** | Section (collapsed when empty) |
-| 535 | **Export** | Section |
-
-### Section ordering (top to bottom)
-1. Node type + name + mask toggle
-2. Position (X, Y)
-3. Alignment (9-grid)
-4. Rotation
-5. Layout / Dimensions (W, H)
-6. Appearance (opacity, hide)
-7. Fill
-8. Stroke
-9. Effects
-10. Export
-
-## Canvas
-
-- Single `<canvas>` element, no id, class `(none)`
-- Parent: `div.view.gpu-view-content` with `inset: 0` (positioned absolutely)
-- Physical size: 1872×1802 (2× DPR)
-- CSS size: 936×901
-- WebGL context: **not exposed** (Figma uses its own GPU rendering, likely via CanvasKit/Skia internally but doesn't expose the GL context to JS)
-- Canvas receives all mouse/keyboard events
-
-## CSS Variables
-- **18,395 CSS variables** defined (massive design system)
-- Figma uses CSS Modules with hashed class names (e.g., `toolbar--horizontalButton--lp3qk`)
-
-## Key Findings for OpenPencil
-
-1. **Toolbar is floating**, not pinned to window bottom edge — sits above canvas
-2. **Three toolbar rows** exist: view tools, design tools, devmode tools (context-dependent)
-3. **Tool groups with flyouts** — Move▾, Frame▾, Rectangle▾, Pen▾, Comment▾
-4. **Properties panel sections** are ordered differently than our plan: Position → Alignment → Rotation → Layout/Dimensions → Appearance → Fill → Stroke → Effects → Export
-5. **Zoom control** is in the right panel header, not the toolbar
-6. **Left panel** has File/Assets tabs, then Pages, then Layers
-7. **Canvas has no accessible WebGL context** — Figma's renderer is fully internal
