# Client-side RPC for the in-browser sequencer-fee preview. The public default
# RPC returns empty data for the NodeInterface precompile on browser-origin
# requests, so the fee row hides without this. Point it at a dedicated RPC
# (e.g. Alchemy: https://arb-sepolia.g.alchemy.com/v2/KEY). Use a
# domain-restricted key for deployed demos - NEXT_PUBLIC_ ships to the client.
