/* =====================================================================
   Mantenimiento — CarArmoring
   Componentes compartidos (reset, nav, botones, section, page-hero,
   project-panel variante --a, footer) copiados verbatim de chalecos.css —
   ver nota de Task 11 del piloto: no se abstraen todavía en un archivo
   común. .cta-banner copiado verbatim de balizaje.css (mismo patrón foto
   circular + texto). Los tres paneles de servicios
   (.service-accordion/.service-details/.service-summary) se muestran
   siempre expandidos (sin collapse); el hover/foco de .service-details
   resalta el marco igual que .vehiculo-card en index.css.
   Todos los colores / tipos / espacios provienen de variables.css.
   (En @media no se puede usar var(); se repiten los px de los breakpoints
    ya definidos en los tokens: 768px, 1024px y 1180px.)
