The pipeline records math.ceil() of a vector preview's intrinsic size while
browsers round naturalWidth, so A4 (595.3pt) and 16:9 slide SVGs failed the
exact-size check with PDF_V3_PREVIEW_GEOMETRY_MISMATCH. The first page showed
"page load failed, retrying" until PDF.js replaced it. SVG previews now allow
a 1px rounding difference; raster previews and the aspect check are unchanged.
Visible pages whose speculative render was cancelled are requeued on slot
release and scroll, and PDF page reads enter the render queue before getPage.
Preview cancellation no longer writes a page failure state.
