/* =====================================================================
   Balizaje — CarArmoring
   Componentes compartidos (reset, nav, botones, section, page-hero,
   project-panel, lightbox, footer) copiados verbatim de venta.css —
   ver nota de Task 11 del piloto: no se abstraen todavía en un archivo
   común. Esta página reemplaza el diagrama de "hotspots" del legacy
   (puntos posicionados en `em` con overrides distintos en 5 breakpoints
   — frágil e imposible de mantener) por una grilla de tarjetas
   icono+etiqueta, responsive por diseño.
   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.)
