Your content will automatically have:\n\n- **📏 A4 page dimensions** with proper scaling\n- **🎭 Professional shadows and borders**\n- **📐 Proper margins and spacing**\n- **📱 Responsive design** for different screen sizes\n- **✍️ Typography optimized** for documents\n\n### Custom Styling\n\nYou can override default styles by targeting the generated CSS classes:\n\n```css\n/* Custom page styling */\n.Page {\n  box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);\n  border: 1px solid #e0e0e0;\n}\n\n/* Custom page content styling */\n.PageContent {\n  padding: 20px;\n  line-height: 1.6;\n}\n\n/* Custom page number styling */\n.PageNumber {\n  font-size: 12px;\n  color: #666;\n}\n```\n\n## 🔧 Advanced Usage\n\n### Custom Page Layouts\n\n```typescript\nPageExtension.configure({\n  bodyHeight: 1123,\n  bodyWidth: 794,\n  pageLayout: {\n    margins: {\n      top: { unit: 'INCHES', value: 1.0 },\n      bottom: { unit: 'INCHES', value: 1.0 },\n      left: { unit: 'INCHES', value: 0.75 },\n      right: { unit: 'INCHES', value: 0.75 }\n    },\n    paragraphSpacing: {\n      before: { unit: 'PTS', value: 12 },\n      after: { unit: 'PTS', value: 12 }\n    }\n  }\n})\n```\n\n### Page Numbering Options\n\n```typescript\nPageExtension.configure({\n  bodyHeight: 1123,\n  bodyWidth: 794,\n  pageNumber: {\n    show: true,\n    showCount: true,\n    showOnFirstPage: false,\n    position: 'bottom',\n    alignment: 'center'\n  }\n})\n```\n\n### Dynamic Configuration Updates\n\n```typescript\n// Update configuration and recompute pagination\neditor.commands.recomputeComputedHtml();\n\n// Or update options directly\neditor.extensionManager.extensions.find(ext => ext.name === 'PageExtension')\n  ?.options = {\n    ...editor.extensionManager.extensions.find(ext => ext.name === 'PageExtension')?.options,\n    pageNumber: {\n      show: true,\n      showCount: true,\n      showOnFirstPage: true,\n      position: 'top',\n      alignment: 'right'\n    }\n  };\n\n// Recompute after changes\neditor.commands.recomputeComputedHtml();\n```\n\n### Custom Node Types\n\n```typescript\nPageExtension.configure({\n  bodyHeight: 1123,\n  bodyWidth: 794,\n  types: ['customBlock', 'customNode'] // Add your custom node types\n})\n```\n\n## 🏗️ Architecture\n\nThis extension is completely isolated and consists of:\n\n- **📦 PageExtension**: Main extension that handles configuration
