/*
 * pp-coa-pdfjs.css — styles for the in-place COA PDF.js viewer.
 *
 * Two surfaces:
 *   1. .pp-coa-canvas   — the crisp PDF canvas overlaid on a COA gallery slide.
 *                         Starts hidden (opacity 0); revealed only once the JS
 *                         has proven a render (.is-ready). If it never renders,
 *                         the underlying <img> shows through unchanged.
 *   2. .pp-coa-modal    — the custom full-document lightbox (all pages, zoom).
 *
 * Palette follows the PP theme (navy + gold) with hard fallbacks so this file
 * is self-contained. Scoped class names only; no global element selectors.
