/* ============================================================================
   M&E CONSTRUCTION GROUP INC — "acero y chispa"
   Negro + dorado, la identidad que el negocio YA usa en todas sus gráficas.
   Motivos, todos sacados de su propio logo/material:
     .truss  → la armadura Warren del logo, repetida como línea sobre el hero
     .bead   → cordón de soldadura (arcos superpuestos) como divisor de sección
     chaflán → esquina cortada a 45° en las tarjetas, como una plancha de acero
   ---------------------------------------------------------------------------
   OJO CON LAS FOTOS: las 17 fuentes son thumbnails de Facebook de 414 px,
   exportadas a 828 con LANCZOS 2x + unsharp. NINGÚN contenedor de foto debe
   pasar de ~420 px de CSS o se ve blanda. Excepción consciente: el render de
   Old San Juan (fuente 361 px) sube a 520 px porque es un render 3D de
   degradados suaves, sin detalle fino que delate el reescalado; y el fondo del
   hero, que va desenfocado y al 28% de brillo a propósito.
