# Standalone Nosterm client deployment.
#
# Serves the static SvelteKit SPA via Caddy on port 8080. This directory deploys
# ONLY the client — point it at a relay of your choice with NOSTERM_DEFAULT_RELAYS
# (runtime, see .env.example). To also run a home relay, use the nosterm-relay
# repo (or set RELAY_UPSTREAM so Caddy's /relay proxy reaches it).
#
#   cp .env.example .env    # then edit
#   docker compose up -d --build
