/* MB Logistic Park — landing premium. Sistema TRAZO (base) + peso de HORIZONTE en hero/números.
   Rediseño 2026-09-14, dirección visual definida por Mario sobre mockups reales (landing/mockups/).
   Mantiene los custom properties (--ink-dim, --warn, --line, --card, --accent, --accent-ink) y las
   clases funcionales del calificador (.qual-step, .qual-progress i, .opt, .selected, .hidden) porque
   assets/main.js y el HTML de #qualifier dependen de ellas — no son decorativas. */
