/* ═══════════════════════════════════════════════════════════════
   S_DevLabs — project demos & animation
   ───────────────────────────────────────────────────────────────
   Every demo is honest about what it is:
     · the voice orb mirrors the REAL states of ai_agent_chat's UI
       (listening / thinking / speaking / idle — taken from its README)
     · the XRPL terminal shows REAL captured values from the public
       XRPL testnet (ledger seq + hash pulled 2026-10-29) with the
       sequence continuing live from that point
   Nothing fakes a transaction, a signature, or a credential.
