"""
Зелёный — доменно-нейтральный пресейл-бот. FastAPI-хендлер.
Мозг — OpenAI-совместимый chat/completions endpoint.
Зрение — VLM-сайдкар, срабатывает только на входящее фото.
Состояние диалога — SQLite по chat_id (открытая линия Битрикса / тред Авито).
Весь домен (бизнес, язык, копирайтинг, маркеры, телефонный формат) живёт в файлах
тенант-пакета: behavior.md, company.md, pricing.md, card_views.json, tenant.json, cards/.
При смене бизнеса код не меняется — меняется только пакет.
