/* =====================================================================
 * SPS · Indicador de carga con la marca (estilo DEMO)
 * ---------------------------------------------------------------------
 * Es el mismo cargador que aprobaste en el DEMO: un cuadrado redondeado
 * con "SPS" en el centro (la P en cobre). El borde gira y las letras
 * hacen un giro 3D. Reemplaza la "ruedita" genérica en todo el sitio.
 *
 * Se carga después de sps-brand.css en cualquier página.
 *
 * Uso mínimo (el JS lo rellena solo):
 *   <span data-sps-loader></span>                    → tamaño normal
 *   <span data-sps-loader data-tamano="sm"></span>   → pequeño
 *   <span data-sps-loader data-tono="claro"></span>  → sobre fondo oscuro
 * ===================================================================== */
