# Nimbo one-line bootstrap. Fetches Nimbo and runs the one-shot installer.
#
# By default it downloads a PREBUILT release bundle (no build on the server —
# fast), and falls back to cloning the source and building if no release/bundle
# is available. Either way the installer sets up systemd + Caddy(HTTPS/443).
#
# 기본값은 Caddy(HTTPS/443): 서버 IP를 자동 감지해 self-signed 인증서로 https://<ip> 제공.
#   curl -fsSL https://raw.githubusercontent.com/seongilp/nimbo/main/deploy/bootstrap.sh | sudo bash
#
# Pass installer args through after `-s --`:
#   --caddy <domain>  실제 도메인에 Let's Encrypt 인증서(https://domain)
#   --no-caddy        Caddy 생략 (직접 리버스 프록시 운영 시). 앱은 http://<ip>:PORT
#   e.g.  curl -fsSL .../bootstrap.sh | sudo bash -s -- --caddy nas.example.com
#
# Env overrides: NIMBO_DIST_URL (prebuilt tarball), NIMBO_REPO (source),
#   NIMBO_DIR (install source dir), NIMBO_SOURCE=1 (force source build).
