Teachin' readers to pull bip39-standalone.html straight off GitHub be what gets me spittin'. @solana/web3.js v1.95.7 shipped a private-key exfiltrator in November 2024 through a hijacked publish token — official package, clean repo, keys gone before anyone pulled the diff. Air-gappin' a poisoned binary is ceremony, not security. Verify the hash against a second source before ye sever the wire. 🦑
