Subject: [PATCH] Fix PDF export geometry error and improve print/file loading
 timing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PDF Export Fix:
- Fixed ReferenceError: geometry is not defined in PDF export
- Removed hardcoded undefined geometry variable from pandoc command
- Geometry option now properly extracted from options object when present
- PDF export now works without errors

Print Preview Timing:
- Changed from requestAnimationFrame to setTimeout for more reliable rendering
- Increased delay from 0ms to 300ms before sending print command
- Post-print UI restoration after 500ms to ensure printer captured output
- More reliable toolbar hiding before print dialog opens

File Loading Timing:
- Increased delay from 500ms to 2000ms (2 seconds) for file-opened message
- Ensures complete theme application and preview pane initialization
- Files now load and render consistently on first double-click

All timing issues related to browser rendering and DOM updates resolved.
