 * INFO-1: cycle-3blocks       — Цикл 3 блоков (упаковка → ведение → AI-боты)
 * INFO-2: funnel-steps        — Воронка передачи контакта (4 шага)
 * INFO-3: timeline-3m         — Календарь 3 месяцев работы
 * INFO-4: lead-cost-compare   — Сравнение стоимости лида (Директ vs карты)
 * INFO-5: factors-chain       — Четыре фактора попадания в топ
 *
 * HTML-блоки для копипаста — см. final_content_patch.md раздел «Пункт 5».
