+# Shibarium heimdall node entrypoint — thin bootstrap sourcing cometbft-common.sh.
+# 
+# Bootstraps a heimdalld node:
+#   1. source cometbft-common.sh for helpers (ct_*)
+#   2. heimdalld init with moniker + chain-id
+#   3. fetch genesis.json from GENESIS_URL if set
+#   4. patch p2p config (bind 0.0.0.0:PORT, external_address)
+#   5. merge seeds from env SEEDS + optional official seed list
+#   6. set persistent_peers from env PERSISTENT_PEERS
+#   7. enable REST server on :1317
+#   8. bind CometBFT RPC to 0.0.0.0:26657
+#   9. exec heimdalld start --home $CMT_HOME --chain <chain> --rest-server
+#
+# Environment:
+#   CMT_HOME       heimdall home dir (default /root/.heimdalld)
+#   CHAIN_ID       shibarium chain id (109 -> mainnet)
+#   GENESIS_URL    URL to fetch genesis.json
+#   SEEDS          comma-separated seed nodes (optional)
+#   PERSISTENT_PEERS comma-separated persistent peers (optional)
+#   IP             external IP for p2p advertisement
+#   MONIKER        node moniker (default d${DOMAIN:-local})
+#   P2P_PORT       p2p port (default 26656)
+#
+# NOTE: heimdall (bone fork) merged REST/LCD into the daemon, so REST runs
+# in-process via --rest-server flag. No separate rest-server subcommand needed.
