Hi, thanks for maintaining the explorer! 🙏

Just a gentle note that this PR is ready for review whenever a maintainer has a moment:

• Both CI checks pass (Build explorer + Check Blockchain Config) ✅
• All declared endpoints are live and responding:
  • RPC https://cosmos-rpc.limonata.xyz — network limonata_10777-1, syncing normally
  • REST https://rest.limonata.xyz — 200 OK
  • EVM JSON-RPC https://rpc.limonata.xyz — eth_chainId returns 0x2a19 (10777)
• The logo resolves from the chain-registry entry, which was merged in Add Limonata Testnet (limonata_10777-1) cosmos/chain-registry#7766.

Happy to make any adjustments if needed. Thanks again!
