Phase 3b of the reader redesign — highlighting for fixed-layout PDFs:
- Select text on a PDF page → same glass popover as EPUBs (colors,
note, copy). The selection's client rects are normalized to
page-fraction quads using a transform-inclusive denominator so
pdf.js's devicePixelRatio scaling on <html> cancels out, then
stored as a JSON anchor {page, rects} in epubcfi_start.
- Rendering goes through the fork's new rect-annotation pipeline
(foliate-js aba68d8): a full-bleed viewBox-0-100 SVG inside the
page iframe, so highlights stay aligned through pan/zoom, iframe
CSS-scaling, and PDF hi-res re-renders with zero re-anchoring.
Frames carry their page index and re-render annotations when
recreated on spread changes.
- Clicking an existing highlight hit-tests in fraction space and
opens the edit popover (recolor, note, copy, delete) at the
host-space click position; drag-selecting text never triggers it.
- Annotations drawer: PDF highlights jump by page index; notes and
recolors round-trip through the same LWW/dedup sync path as EPUBs
(same dedup key derivation on the JSON anchor).
- Comics keep bookmark-only highlighting (no text layer) by design.
