# ---------------------------------------------------------------------------
# Cinder is a TUI; `docker compose up` only streams log bytes and does NOT
# allocate an interactive PTY connecting your shell to the container, so the
# binary starts but your terminal stays blank. Use `compose run` instead:
#
#     docker compose build                        # one-time / after changes
#     docker compose run --rm cinder
#
# `compose run` automatically allocates -it for the user's terminal.
#
# Optional overrides via your shell environment (or your local .env):
#   RPC_URL        (optional) Solana JSON-RPC HTTP; forwarded when set; else the
#                  binary uses SOLANA_RPC_URL or its built-in default (see config).
#   RPC_WS_URL     (optional) WebSocket endpoint; derived from RPC_URL if unset
#   RUST_LOG       (optional) tracing filter, e.g. "phoenix_sdk=warn,info"
