Architecture

Editor (facade)
├── EditorContext (shared state)
│   ├── ContentService → ToastMark
│   ├── PreviewService → Renderer + DOMPurify
│   └── EventBus (typed pub/sub)
├── MarkdownMode
├── PluginManager
└── Layout UI

Design patterns used:

• Facade — Editor / Viewer public API
• Observer — typed EventBus
• Composition — services injected via EditorContext
