   MATRICES — zona interactiva
   ═══════════════════════════════════════════════════════════════════════
   Se monta sobre la hoja de Inspecciones (module-insp.css): bienvenida,
   tira de datos, tres columnas, paneles, respuestas y botones son los
   mismos. Aquí va lo propio de la matriz: la lista de peligros con su
   nivel, las escalas de la GTC 45, la fórmula en vivo, la pirámide de
   controles y la matriz final.

   Sin cajas ni líneas que dividan: el contenido se separa con aire. El
   semáforo de riesgo (rojo, naranja, amarillo, verde) es el de la guía.
