# Description of Changes
Upgrades embedPDF from v2.5.0 to v2.6.0 and migrates from unmaintained
pdf-lib to @cantoo/pdf-lib fork. Adds defensive error handling for
malformed PDFs and improves bridge lifecycle management.
### Changes
**Dependencies**
- Upgrade all @embedpdf/* packages from ^2.5.0 to ^2.6.0
- Replace pdf-lib with @cantoo/pdf-lib (maintained fork with better
TypeScript support)
**PDF Viewer Infrastructure (attachment/bookmark fix)**
- Add useDocumentReady hook to track document lifecycle across bridges
- Implement defensive bridge cleanup to prevent stale registrations
- Fix race condition in document ready state detection by subscribing to
events before checking state
**Link Extraction (updated to cantoo/pdf-lib)**
- Add graceful error handling for PDFs with invalid catalog structures
- Extract enhanced link metadata (tooltips, colors, border styles,
highlight modes)
- Return empty results instead of throwing on malformed PDFs
- Add validation for link creation (destination page bounds, rect
dimensions, color values)
**Signature Flattening (updated to cantoo/pdf-lib)**
- Improve SVG embedding with three-tier fallback strategy (native
vector, rasterized PNG, placeholder)
- Add proper Unicode handling for PDF form tooltips via
PDFString.decodeText()
- Extract SVG utilities into cleaner strategy pattern
**Form Field Processing (updated to cantoo/pdf-lib)**
- Add support for display labels vs export values in dropdown/list
fields per PDF spec 12.7.4.4
- Implement caching for expensive field property lookups
- Add proper handling of malformed /Opt arrays
