Two bugs broke the Phase 3b PDF highlight flow end to end:
1. Selection capture never attached: reader.ts read renderer.isPDF
before view.init() rendered the first spread, but the renderer
only sets that flag once frames exist (PDF frames carry pdf.js
onZoom). The stale undefined copy gated the pointerup selection
listener off, so selecting PDF text did nothing. The listener now
gates structurally on the loaded document having a .textLayer
(true for every PDF page, false for comics), and isPDF is re-read
after init — which also finally makes the Smart|Pan|Text control
and the saved pointer mode apply on PDFs.
2. Highlights rendered invisibly: the overlay SVG lived inside the
page iframe, whose <html> pdf.js scales by 1/devicePixelRatio —
shrinking the overlay into the top-left corner on any dpr != 1
display. The fork (1c0ebf3) now renders annotation rects
host-side, inside the frame wrapper element, positioned in
percentages of the visible page box — immune to the html
transform, zoom re-renders, comic iframe scaling, and pan/zoom.
