# lib-onboarding.sh — мастер первичной настройки (тонкий оркестратор).
#
# Иерархия: язык → транспорт → провайдер → модель → preflight → ключи.
#
# Constructor Pattern: этот файл — только координация. Логика по слоям:
#   lib-onboarding-registry.sh — парсеры providers/models.toml + fallback
#   lib-onboarding-ui.sh       — pick_* функции (whiptail/bash select)
#   lib-onboarding-state.sh    — запись secrets/.env + onboarding.toml + флаг
#   lib-preflight.sh           — провайдер-специфичные CLI-проверки
#   lib-i18n.sh                — STR_* словарь + load_lang
#
# Источник: $KIT_DIR/_blocks/registries/{providers,models}.toml (submodule
# kei-registries). Если submodule не подтянут — fallback (см. registry.sh).
#
# Skip: $ONBOARDED_FLAG, env KEISEI_SKIP_ONBOARD=1, non-TTY.

# Глобалы заполняемые мастером.
