Test Plan

• git diff --check
• Docs build not run locally because website/node_modules is not installed and the repo has no committed website lockfile

Thanks for this, and for tackling #36279! We went with #38811 (merged in 99cee12), which addresses the same issue — it places the caution before the docker run block (so the warning lands before the user pastes), names the specific corrupted flags (-v, -e), and was Docusaurus-build-verified. Closing this as superseded. Your literal ssh user@your-server snippet was a nice touch and could still be folded in as a follow-up. Appreciate the contribution!
