 * Shell común para infovivo.app
 *
 * Estilos compartidos por todas las páginas estáticas (legales,
 * reset-password, futuras): variables de marca, tipografía,
 * header sticky con nav, footer 4 columnas + social y breakpoints
 * responsive.
 *
 * La home (index.html) tiene sus propios estilos inline porque su
 * estructura (hero + secciones) es distinta. Pero el chrome (header
 * y footer) lo extraemos aquí para que cualquier página nueva pueda
 * heredarlo sin duplicar 200 líneas de CSS.
