/**
 * Tests para la página 1 rediseñada del PDF ROI — Etapa 6 Sprint 1.5.
 *
 * Verifica:
 * - drawRoiPage1 invoca los bloques clave (hero, top3, grid, banner)
 * - exportToPdf ROI llama addPage 4 veces (5 páginas)
 * - Ninguna página ROI usa landscape
 * - El hero llama setFontSize(28) para la cifra principal
