- Add tauri/ subfolder: a Tauri-based desktop shell that loads the same index.html as the Electron app, producing a ~2MB installer (vs ~71MB for Electron) by using the OS WebView2 instead of bundled Chromium. Includes sync-frontend.js to keep tauri/dist/ in sync with the canonical index.html and vendor/ at build time (no UI duplication/drift). - Vendor lucide, jsPDF, and jspdf-autotable locally under vendor/ instead of loading from CDNs, so the app works fully offline in both shells. - Fix server.js path traversal vulnerability (sanitize/contain request paths). - Fix exportPDF() using stale/edited piece data that could produce Infinity/NaN in generated PDFs; add a recalculate guard. - Fix race conditions: overlapping copy/save-defaults button revert timers, and FileReader callbacks for logo/CSV import that could apply out of order. - Minor cleanups: explicit array index parsing, hasResult() helper, consistent event binding for NMFC search results, cached DOM lookups. - Document the dual-shell architecture and vendoring conventions in CLAUDE.md.
