Add functional page number and running title toggles with proper positioning
for left/right pages. Implement smooth crossfade transitions between iframe
reloads to eliminate visual flicker during PagedJS rendering.
Page Numbers & Running Titles:
- Page numbers toggle: adds counter(page) to @bottom-left (left pages) or
@bottom-right (right pages)
- Running title toggle: adds string(title) from h2 chapter titles
- Combined positioning: both elements appear side-by-side in same margin box
- Left pages: "1 Chapter Title" in @bottom-left
- Right pages: "Chapter Title 2" in @bottom-right
- Automatic CSS rule management: adds/removes @page:left, @page:right, and
string-set rules based on checkbox state
- Bidirectional sync: checkboxes reflect existing CSS state on load
Smooth Iframe Transitions:
- Dual iframe system: two iframes alternate as visible/hidden
- Crossfade technique: hidden iframe loads new content while visible remains
displayed, then smooth 300ms opacity transition
- Scroll preservation: saves scroll percentage from visible iframe, restores
to hidden iframe after PagedJS render
- Collision prevention: isTransitioning flag prevents overlapping renders
- Active frame tracking: computed property ensures ElementPopup always
references the visible iframe
Technical details:
- Uses srcdoc to inject HTML with dynamic CSS
- Z-index and opacity manipulation for layering
- CSS transitions (opacity 0.3s ease-in-out)
- Automatic frame swapping after transition completes
