Environment Variables Are Unavailable

The invite-only disposable DEV beta serves static files and does not run a customer process. Runtime environment variables are unavailable.

Repository builds and repository build-time environment configuration are unavailable and server-side closed. Build the disposable public output before the walkthrough, inspect it, and upload only the resulting directory through the documented direct static upload.

Every value embedded in static output is downloadable by visitors. Do not put tokens, credentials, personal data, or private configuration in uploaded files.

This page is an explicit unavailability notice, not a setup guide.
