Summary
Wire the Solace Bank Group PLC portal to real, deployed backends so it stops showing 100% static sample data. All seven portal pages (Dashboard, Accounts, Treasury, Reporting, Compliance & Risk, Settlements, Transaction Builder) now overlay live data from the two browser-reachable services on the Chain 138 estate.
https://rpc.d-bis.org(Besu/QBFT, chainId0x8a=138), read-only viaethersv6.https://api.explorer.d-bis.org/api/v2(Blockscout, CORS*).Backends that are not browser-reachable today stay explicitly labelled:
BFF required(yellow); orchestrator BFF route scaffolded on a separate branch (devin/1776587283-proxmox-bff).Mocked(grey).Scope
