/* --- Pagination -------------------------------------------------- */
/* Scoped to the paginator rather than to `nav[aria-label]`. The bare attribute
   selector matched every labelled nav on the site — tab strips, subnavs, the
   wiki docs sidebar, breadcrumbs — and turned each of their links into a 32px
   bordered pill, because it outranks a single-class rule such as
   `.notification-tabs a`. What it was written against is the Bootstrap 4
   paginator (a `> div` wrapper around a `span[aria-current="page"] > span`);
   both paginators here are `nav.df-pagination` and are styled by their own
   `.df-pagination .page-link` rules further down this file. Scoping keeps the
   one part that still matches — the admin paginator's meta row is a direct
   child div — and releases everything else. */

/* 徽章主色。卡片通过内联自定义属性 --df-badge-color 带入（见 partials/badge-card.blade.php），
   不写内联颜色，暗色主题跟得住。

   只染描边和底色，不染文字：这个颜色由管理员在后台填写，明暗不可控，
   拿它染 h3 会在浅色主题下把徽章名变成看不清的字。
   描边是纯装饰、底色只有 6% 混入，任何色值都不会压过正文对比度。

   未获得（is-locked）的徽章刻意不染色，保持既有的置灰处理，
   让「已点亮」和「未点亮」不读文字也能分辨。

   这一段写在 body.theme-light 里即可同时作用于 light-new 和 dark-new：
   两者 body 都带 theme-light，暗色只覆盖变量（--df-system-surface 随 --surface 变深）。 */
