# Design: Sync Variables, Image Export, CLI, Core Extraction

## Approach

Documentation-only change. Update specs and docs to match implemented features.

## Delta-Specs

### scene-graph — variables system (types, collections, modes, bindings, resolution)
### editor-ui — VariablesPanel, FillSection variable picker, ExportSection, splash loader
### canvas-rendering — variable binding resolution in renderer, image export rendering
### desktop-app — monorepo structure, @open-pencil/core and @open-pencil/cli packages
### tooling — Bun workspace, CLI commands, npm publishing
### testing — 7 variable unit tests
