/**
 * PDF viewer — branded RTL presentation around the BROWSER's native PDF
 * renderer (never a JS library — PDF.js mis-renders Hebrew).
 *
 *   • Desktop: a framed <object> (native renderer) + slim toolbar.
 *   • Phones:  a card that opens the file in the device's native viewer.
 *
 * Progressive enhancement: the native <object>/link render normally until
 * pdf-viewer.js adds `.is-enhanced`; the hide rules are gated on that class,
 * so there is no FOUC and the PDF stays correct even if the script never runs.
 *
 * NOTE: every selector targets JS-injected markup, so this file is safelisted
 * against WP Rocket "Remove Unused CSS" in inc/assets.php
 * (hm_rocket_rucss_exclusions), and pdf-viewer.js is excluded from WP Rocket
 * "Delay JavaScript" (hm_rocket_delay_js_exclusions) so it enhances on load.
 *
 * @package Hamechadesh
