/* Comunicación y Colaboración — Retos (docs/render-colaboracion-retos.cjs). Two editorial columns: the existing header
   with a photo of videoconference equipment right under it (left), and the six challenges (right), separated by space
   only. The section header keeps its styles from colaboracion-page.css; the old full-width background photo is
   switched off here. Fuchsia #CD0298 for the numbers and line icons. The challenges stay descriptive (no links); on
   devices with a precise pointer a soft fuchsia glow and a very slight scale acknowledge the hover. */
