/* vtx-intro-blockquote-20261114-v4.css
 *
 * 1) Background intro (.vtx-reader-context) lives in the post header
 *    (#post-info, after #post-meta), not in the article body.
 *    White typography on the cover, left-bar blockquote, still a
 *    native <details>/<summary>. The header grows when expanded
 *    (theme-hao gives #page-header.post-bg a fixed height and
 *    overflow:hidden).
 *
 * 2) Cover like/download (#vtx-cover-acts) is mirrored to the left
 *    to match #vtx-permanent-langswitch: same edge inset (20px
 *    desktop, 12px mobile) and the same vertical center. Visual
 *    styling of the buttons is unchanged.
