   SECCIÓN WORKFLOW + diagrama orgánico
   --------------------------------------------------------
   Diseño orgánico: nodos circulares con glow de color
   distribuidos en el canvas. Líneas en ángulo recto entre
   nodos con dos comportamientos:
     - Líneas internas: conectan nodos dentro de la zona central
       (que coincide aproximadamente con el ancho legible del
       contenido del sitio).
     - Líneas externas: salen desde los bordes del viewBox
       (x=0 y x=1600), que coinciden con los bordes del viewport
       porque el SVG ocupa width:100% del .section-workflow (que
       no tiene padding horizontal). Efecto: las líneas parecen
       continuar fuera del frame visible mientras los nodos se
       mantienen en la zona central legible.
   Sin tooltips ni interactividad: los nodos son decoración pura.
   El hover solo refuerza el glow sutilmente.
