357-397: Documentation expansion for environment variables is clear and well-structured.

The expanded guidance effectively covers environment variable loading across Node, Deno, and Bun runtimes with appropriate examples and fallback instructions for Node <v20. The tabbed content organization and step-by-step dotenv setup are helpful additions. Once the Deno syntax is corrected, this section will provide good guidance for users.
