/* Emma — estilos del sitio público.
 *
 * Mobile-first. Dos layouts sobre los mismos tokens:
 *   - Ancho completo: landing y páginas legales.
 *   - Columna angosta (.container): el formulario de registro.
 *
 * Paleta tomada de los mockups de producto: azul #4C70F5 sobre tinta #1F1F3A.
 *
 * Convención de botones: .btn es de ancho automático. Los botones que deben
 * ocupar todo el ancho —los del formulario— llevan además .btn-block. Ojo al
 * añadir variantes: no volver a poner width en .btn o los CTA de la landing se
 * estiran de punta a punta.
