/* ==========================================================================
   parts/horse-pedigree.css — the full-pedigree PDF box (parts/horse/pedigree.php + assets/js/parts/horse-pedigree.js).
   Live: `div#pedigree-full.self--center` > `#brxe-qccrkb` (flex, centred) > `.wppdfemb-frame-container-1` (width 900px,
   capped by the parent) > PDF Embedder iframe whose viewer sets it to 771 px tall (BEHAVIOUR-R2 §2.2.3):
   900 / 696 / 348 × 771 at 1440 / 768 / 390. Closed = display:none (the `hidden` attribute; base.css [hidden]).
   Open: pages are canvases at the frame width, stacked in a 771 px scroll box with a hidden scrollbar; a 32 px toolbar
   (page n / N, zoom −/+, download) sits over the bottom edge while the pointer is over the box (live's toolbar is
   hover-only) or focus is inside it; always shown without hover (touch). The page background stays the section's navy.
