/*
 * Star Obras — sistema visual común (inicio, ingreso, ayuda y barra del panel).
 * Lenguaje de diseño tomado de starlink.com (relevado el 2026-10-19 con el navegador):
 *   fondo negro #000 y texto #FAFAFA · tipografía tipo DIN (Starlink usa DIN; acá Barlow, libre en Google Fonts)
 *   títulos 64/48/24 px en 700 · cuerpo 16/24 · botón sólido blanco con texto negro, 4 px de radio, 6 px 32 px, 14 px 700
 *   portadas de 100vh con imagen "cover" y degradés hacia negro · contenedor de 1200 px con columna de texto de 600 px,
 *   alternando izquierda/derecha · aparición al hacer scroll (opacity + transform, 0,5 s ease-out)
 *   barra superior transparente sobre la portada: logo a la izquierda, menú al centro · menú a pantalla completa en el celular.
 * La marca (nombre, logo con casco, ámbar y acero) se mantiene; el ámbar se aclara a #FF9F1C para leerse sobre negro.
