# Overlay для слабого VPS (4 vCPU, 4 GB RAM).
# Применять как: docker compose -f docker-compose.yml -f docker-compose.vps.yml up -d --build
#
# Главное:
#  - worker concurrency=1, max-tasks-per-child=3 (Chromium быстро течёт)
#  - IAAI_PARALLEL_TABS=4 (важно: каждая вкладка ~80-150 MB)
#  - IAAI_MAX_PAGES_PER_RUN=200, IAAI_MAX_VEHICLES_PER_RUN=2000 — короткие тестовые прогоны
#  - hard memory limits на каждый сервис
