/* Apptonomia — locale picker (dropdown de siglas).
   Estilos del componente reutilizable. Cada app lo carga con UN solo
   <link rel="stylesheet" href="assets/css/locale-picker.css">.

   Diseño:
   - Botón compacto: sigla uppercase + chevron.
   - Panel flotante debajo del botón con sombra suave.
   - Opciones: sigla uppercase + nombre nativo, alineados.
   - Animación de 120ms al abrir/cerrar.
   - Hover y foco accesibles (WCAG AA).
   - Responsive: en móvil el panel ocupa el ancho disponible.

   Las apps pueden sobreescribir variables CSS (--lp-bg, --lp-border,
   --lp-text, --lp-accent) para adaptar el componente a su paleta
   de marca sin tener que tocar el CSS. */
