/* The in-site PDF viewer (templates/default/viewer.jinja, js/pdf-viewer.js; owner order 2026-10-18). Colors come from the
   --site-* tokens (set on .site-page, light and dark), the head band stays navy in both themes like every hero, square
   corners and 1px hairlines as everywhere else. Controls are at least 48 px tall so a thumb can hit them. */
