# client. Non-interactive — the operator-facing "Create a bot" instructions
# and token paste live in setup/auto.ts. The token comes in via the
# TELEGRAM_BOT_TOKEN env var.

# Emits exactly one status block on stdout (ADD_TELEGRAM) at the end. All
# chatty progress messages go to stderr so setup:auto's raw-log capture
