/* Hover quote bubbles (plugins/quote-pop).
 *
 * Source syntax: a blockquote starting with 🗨; plugins/quote-pop/index.js
 * turns it into

 *   <span class="quote-pop" tabindex="0">
 *     <span class="quote-pop-label">论文原文(§II)</span>
 *     <span class="quote-pop-body">
 *       <span class="quote-pop-para">…original paragraph…</span>
 *     </span>
 *   </span>
 *
 * and lifts the trigger to the end of the preceding paragraph, so it reads
 * inline like a link (dashed underline below the text). By default the body
 * is hidden; hovering / focusing the trigger opens the floating quote card.
 * Tune per page with the variables below. */
