# bitcoin-cli wrapper for Umbrel/Docker deployments.
#
# PyBLOCK's modes A/B call bitcoin-cli directly via subprocess. Inside the
# Umbrel container we connect to the host's Bitcoin Core (or Knots) over the
# Docker network using the credentials Umbrel injects through APP_BITCOIN_*
# env vars (re-exported by the entrypoint as BITCOIN_RPC_*). This wrapper
# turns every `bitcoin-cli` call into a properly-authenticated remote RPC
# call against that node.
