/* GraphChinese — 分享 Shareables catalog (assets/shareables.js).
   Built from the shared tokens in styles.css, so it inherits dark mode instead
   of declaring its own. The thumbnails are canvases drawn by card-studio.js and
   already carry their own paper — this file only frames them.
   Mobile first: one column on a phone, and every tap target clears 44px. */
