/*
 * Live-blog enterprise rebuild — stylesheet for all P1-P5 + A1-A10
 * markup classes. Loaded on:
 *   - Article reader pages (via header.php gated on $isArticleExperiencePage)
 *   - /live hub index (direct <link> in live/index.php)
 *   - Admin manage / desk / desk_mobile (direct <link>)
 *
 * Split into 3 sections:
 *   §1  Bootstrap 5.3+ utility polyfill (project loads Bootstrap < 5.3 in
 *       parts; these classes appeared in 5.3 and the templates depend on
 *       them. Subtle background + emphasis text + .vr separator.)
 *   §2  Public reader-surface classes (P1-P5)
 *   §3  Admin authoring-surface classes (A1-A10)
 *
 * All keyframes consolidated here so the inline <style> blocks in
 * the admin views (desk.php, desk_mobile.php, /live index.php) can
 * be retired in a future cleanup pass.
