/* ---- "text" mode: a positioned, real-text reconstruction of each PDF page ----
   Each page is one fixed-size "sheet" (sized in pt, matching the PDF's own
   page size) holding absolutely-positioned real text spans, filled rects,
   rule lines and images -- not a picture of the page, actual selectable
   HTML styled to sit exactly where the PDF put it. */

/* The black page border lives on .pdf-sheet-wrap, not .pdf-sheet:
   .pdf-sheet is what gets transform:scale(--fit-scale)'d to fit narrow
   viewports, and a border on a scaled/transformed element gets resampled
   along with it, which can blur one edge into gray instead of solid
   black. .pdf-sheet-wrap is never transformed, so a border here always
   paints crisp. That in turn only works if the *wrap's own box* lands on
   a whole device pixel -- render.php now rounds the wrap's width to an
   integer px for exactly this reason (a raw PDF page width in points,
   e.g. A4's 595.32pt, almost never converts to a whole pixel). The wrap
   uses default content-box sizing, so the border sits *outside* its
   declared (pixel-rounded) width/height, with the sheet -- sized in pt,
   matching the wrap almost exactly but not sub-pixel-exactly -- flush
   against the inside of it. overflow:hidden trims that sub-pixel sliver
   and, more importantly, keeps .pdf-sheet's own box-shadow (a soft drop
   shadow around the page) from bleeding across the border itself and
   washing it out at the edge where the two would otherwise overlap. */
