+### Completed Modifications (Round 11)
+
+1. **DrawingCanvas Integration Fix**
+   - Replaced placeholder div with actual DrawingCanvas component rendering in notebook pages
+   - Passed backgroundType from currentPage.background (with fallback to notebook.notebookType)
+   - Passed initialDrawingData from currentPage.drawingData
+   - Added handleDrawingSave callback to save drawing data to page + create version
+   - Added onExit callback to toggle drawing mode off
+   - Added drawing indicator badge in save bar when page has drawingData
+   - Added "Edit Drawing" button in save bar when page has drawingData and not in drawing mode
+   - Added drawing indicator icon on PageThumbnail for pages with drawingData
+
+2. **Notebook Versioning**
+   - New Prisma model: `NotebookPageVersion` (id, pageId, version auto-incrementing, textContent, drawingData, editedBy, editSummary, createdAt)
+   - Added versions relation to NotebookPage model
+   - API endpoint `/api/notebooks/[id]/pages/[pageId]/versions/route.ts`:
+     - GET: List all versions of a page (ordered by version desc)
+     - POST: Create a new version from current page content
+     - PUT: Restore a specific version (creates pre-restore snapshot + restored version)
+     - Max 50 versions per page enforcement (deletes older ones)
+   - Version History UI:
+     - VersionHistoryDialog component with visual timeline (dots + connectors)
+     - Timeline dots: emerald pulsing for current, emerald solid for previewed, gray for others
+     - Version entries show: version number, "Current" badge for latest, edit summary badge, timestamp
+     - Content preview with HTML stripped to plain text (line-clamp-2)
+     - Drawing indicator on versions with drawingData
+     - "Restore version" button with AlertDialog confirmation
+   - Auto-versioning on save (manual save + drawing save)
+   - Version creation is non-critical (try/catch, failures don't block the save)
+
+3. **Student Login Workflow**
+   - Enhanced auth-view.tsx with 3-tab login: Teacher/Admin, Student, Parent
+   - Student tab: School ID field, simplified interface, info message about accounts created by teachers

+   - Animated role icons on left illustration panel
+   - Forgot Password link with role-specific demo info
+   - Role-specific welcome messages after login

+   - Bulk student account creation: default password, email domain, student selection with checkboxes
+   - STUDENT and PARENT roles added to user role selector
+
+4. **Parent Portal**
+   - New Prisma model: `ParentStudentLink` with relations to User, Student, School
+   - API routes: `/api/parent-links/route.ts` (GET, POST, DELETE) and `/api/parent-links/[id]/route.ts` (GET, PUT, DELETE)
+   - ParentDashboard component with:

+   - Updated Calendar Events API (POST/GET/PUT/DELETE) with recurring event support and child event generation
+   - Edit series/instance dialog with series/instance edit modes and delete modes
+   - Recurring event UI: repeat type, interval, days of week selector, end options

+
+6. **Grade Report PDF Generation**
+   - Enhanced Grade Report PDF API: template selection (short/full/custom), student avatars, grades table, eco watermark
+   - On-the-fly generation by studentId
+   - Reports View enhancements: PDF generation button (FileDown), template selector, batch generate, download history
+
+7. **Data Import/Export**

+   - Settings View: import drag-and-drop zone, type selector, progress indicator, import summary, sample downloads
+
+8. **Styling Improvements**

+   - Page thumbnails: hover shadow effect, drawing indicators
+   - Global CSS additions: .animate-slide-in, .animate-slide-out, .animate-pulse-dot, .canvas-toolbar, .version-timeline
+   - File drop zone (.file-drop-zone), import progress (.import-progress), report preview (.report-preview), eco watermark (.watermark-eco), badge type (.badge-type)
+
+9. **100+ New i18n Keys**
