/* AI Summary Buttons – style "card" (dark or light card). Loaded after the
 * base stylesheet (ai-summary-buttons.css) only where a box uses this style.
 * Own look, not inherited from the theme; a theme overrides the
 * --asb-card-* tokens, the class asb-card-light (on the box or a parent)
 * switches to the light card ("Automatic" sets it from the background). The 3 px top bar shows the reading progress
 * (JS sets --asb-progress on boxes with ai-summary-buttons--progress);
 * without JS, or with the option off, it is a full static accent. */
