#
# Installs into ./primora (override with PRIMORA_DIR). On a fresh install,
# interactive shells get one question — the URL the app will be opened on
# (domain or IP, optional port). Non-interactive:
#   PUBLIC_URL=https://primora.example.com bash install.sh
#   DOMAIN=192.168.1.50 NGINX_PORT=8085 bash install.sh   (legacy form)
#
# https URLs mean TLS terminates at your own proxy in front of Primora's
# bundled nginx (which always speaks http on NGINX_PORT).
#
# Pulls prebuilt GHCR images when available; otherwise downloads the source
# tarball and builds locally. Either way the result is the same compose stack.
