When AI generates whiteboard elements that exceed the fixed 1000x562.5 canvas, content was clipped by overflow-hidden with no way to view it. This commit adds interactive navigation to the whiteboard: - Auto-fit: when elements overflow, content is scaled and centered to ensure nothing is clipped (with 24px padding) - Drag-to-pan: hold and drag to pan around the whiteboard - Scroll-to-zoom: mouse wheel zooms in/out (0.2x to 5x range) - Double-click or Reset View button to return to default view - View auto-resets when new whiteboard content loads When content fits within the canvas, behavior is unchanged - no extra cursor, no transforms, no visual regression. Fixes THU-MAIC#19

What
Enable uploading Markdown (
.md,.markdown) and plain text (.txt) files as course material, alongside existing PDF support. Text files bypass the OCR pipeline entirely — their content is read client-side and passed directly to the generation pipeline.Why
Many users have learning materials in Markdown or plain text format. Previously, the upload UI only accepted
.pdffiles, requiring users to convert their notes before uploading.Changes
components/generation/generation-toolbar.tsxacceptfilter to.pdf,.md,.txt,.markdown; addisSupportedFile()helper; update UI labelapp/page.tsxFileReader.readAsText()to populatepdfTextdirectly, skippingstorePdfBlob()and OCRlib/i18n/common.tsdocUploadi18n keylib/i18n/generation.tsHow it works
The generation-preview page already checks
hasPdfToAnalyze = !!pdfStorageKey && !pdfText— whenpdfTextis already populated (text files), it skips directly to outline generation. Zero changes needed in generation-preview.Extensibility
The
isSupportedFile()helper and extension-based branching make it easy to add more formats (.docx,.csv, etc.) in the future.Testing
npx tsc --noEmit).mdfile → content passes to generation.txtfile → content passes to generation.pdffile → existing OCR flow works (no regression)
