# shellcheck shell=bash
# lib-onboarding-ui.sh — pick_* функции мастера (whiptail / bash select).
#
# Constructor Pattern: 1 файл = UI слой. Парсеры реестров — в registry.sh,
# state-запись — в state.sh.
#
# Заполняет глобалы:
#   ONBOARDING_LANG, ONBOARDING_TRANSPORT, ONBOARDING_PROVIDER, ONBOARDING_MODEL
#   ONBOARDING_AUTH_ENV_KEYS[] + ONBOARDING_AUTH_ENV_VALUES[]
#
# Использует:
#   - lib-i18n.sh: STR_* словарь + i18n_available_languages + i18n_load_lang
#   - lib-onboarding-registry.sh: списки провайдеров/моделей

# Read a validated 1-based menu choice. Non-numeric or out-of-range input is
# rejected with a re-prompt instead of crashing: bash arithmetic $((ans-1))
# treats a non-numeric "ans" (e.g. the user typing "claude") as a variable name
# → "unbound variable" under `set -u`. $1=option count, $2=prompt.
# Echoes a number in [1,$1] on stdout; prompts/warnings go to stderr.
