/**
 * MC LearnPress UI — styled select.
 *
 * Pairs with assets/js/select.js. Site-wide: this sheet is loaded on every
 * frontend page, so it depends on tokens.css only — never on base.css, whose
 * rules are scoped to `.mc-lp` and would not apply outside plugin screens.
 *
 * Two states exist by design:
 *
 *   < 768px  the native <select> is visible and styled directly. The OS picker
 *            handles the open state, which is better on touch than any custom
 *            panel. The custom trigger is hidden.
 *   >= 768px the native <select> is visually hidden (but still present, focusable
 *            via its label, and still submitting) and the custom trigger + panel
 *            take over.
 *
 * Logical properties only — zero physical left/right, so it mirrors correctly
 * under dir="rtl".
 *
 * @package MC_LearnPress_UI
 * @since   1.1.0
