/**
 * Petsure course archive styles.
 *
 * Powers the Petsure-owned course archive page (themes/petsure/tutor/
 * course-archive.php): filter sidebar, active-filter chips, course grid and
 * pagination. All colors and radii come from the design-system tokens defined
 * in the theme :root (no fallbacks).
 *
 * Self-contained: the archive cards render .petsure-btn buttons, so the base
 * button styles are duplicated here from petsure-core's button.css /
 * elementor-widgets.css. That keeps the archive styled when the plugin is
 * deactivated — the same pattern as woocommerce.css in this theme — while the
 * plugin keeps providing the shared button system for its Elementor widgets.
 *
 * @package Petsure
