- Measure page positions via first card's getBoundingClientRect
(page wrappers use display:contents so have no box)
- Convert individual cards to placeholders when scrolling away
(store HTML in jQuery data, set fixed dimensions, empty content)
- Restore cards from placeholders when scrolling back
- Calculate current page based on which page's top is closest
to viewport bottom without being below it
- DLP (Desired Loaded Pages) = [CP-2, CP-1, CP, CP+1, CP+2]
- Load one page at a time via AJAX
