/**
 * Convención de iconos (Lucide) — reemplazo de emojis en <h3> de tarjetas.
 *
 * En vez de anteponer un emoji (ej. "📊 Pilar 1: ...") al texto de un <h3>,
 * usar un icono SVG real de Lucide así:
 *   <h3><i data-lucide="bar-chart-3" class="card-icon"></i> Pilar 1: ...</h3>
 *
 * Requisitos para que funcione:
 *   1) Cargar el script de Lucide (versión pineada, no @latest) antes de js/main.js:
 *      <script src="https://unpkg.com/lucide@0.469.0/dist/umd/lucide.js"></script>
 *   2) js/main.js llama a lucide.createIcons() en DOMContentLoaded, lo cual
 *      convierte cada <i data-lucide="..."> en un <svg> real.
 *   3) El estilo visual del icono (tamaño, color, alineación) lo controla la
 *      clase .card-icon definida más abajo en este archivo.
 *
 * NOTA: el reemplazo real de los emojis dentro de cada <h3> es tarea de copy/
 * contenido y se hace en un paso posterior — este bloque solo documenta la
 * convención para que sea consistente en toda la migración.
