# Interactive installer for Docker + (optional) Certbot SSL + Calagopus Wings (calagopus/wings)
# Intended usage:
# curl -fsSL https://example.com/install-wings.sh | bash
#
# Notes:
# - Prompts read from /dev/tty so it still works when piped from curl.
# - Default answers are conservative (Docker install: NO, SSL setup: NO, reboot: NO).
