/* =====================================================================
 * Mud Multilingual Translation – frontend styles
 * Prefix: mud-multilingual-translation-  (full directory name slug)
 *
 * Top bar: a single toggle button that opens a dropdown of languages.
 * Floating button: globe icon that opens its own language list.
 *
 * Design goals:
 *  - Sit lightly on the page (no full-width background, minimal padding
 *    so it does not push the theme's header / content around).
 *  - Use inline-flex with theme-friendly colors so it blends with the
 *    active WordPress theme instead of fighting it.
 *  - Force the dropdown to display correctly even if the theme tries
 *    to override it (we add !important to the display rules only).
 * ===================================================================== */
