- Quick Start step 3 now lists BASE_NODE_L1_ETH_RPC and BASE_NODE_L1_BEACON
  alongside the OP_NODE_* vars; reth (base-consensus) is the default client
  and silently fails to connect to L1 without them (closes #1073)
- Configuration > Required Settings adds a base-consensus L1 block mirroring
  the op-node block so the docs stay in sync with .env.mainnet/.env.sepolia
- reth/README.md Setup section: "devnet" corrected to "sepolia" (closes #1075)
