/* Sofisis 2026 — shell compartido: barra de navegación, pie y botón flotante.
 *
 * Lo carga TODO el sitio, incluidas las páginas viejas que siguen sobre bootstrap
 * (documentación, registro, login, blog). Por eso aquí no hay reset global ni
 * reglas sobre body/h1/h2/.btn: cada selector va bajo el prefijo `.s26-` y cada
 * token bajo `--s26-`, de modo que este archivo no pueda pisar a bootstrap ni al
 * theme viejo. Los estilos del cuerpo de la portada siguen en home_2026.css y los
 * de las páginas interiores en pages_2026.css.
