/*
 * OPLEX — custom drop-down date picker styles.
 *
 * Companion to frontend/shared/js/oplexDatePicker.js. Two themes:
 *   - dark (default) — matches admin-standalone tokens
 *   - light          — opt-in via [data-theme="light"] on a parent element
 *
 * The native <input type="date"> stays in the DOM but is visually clipped
 * (not display:none, so it still ships its value with the form).
