Docs Request: Add documentation for feature flags and environment-based configuration #2864
Description
What is the issue you are encountering with the docs?
Environment-based behavior and feature flags in base/web are not documented in a centralized place, making it difficult for contributors to understand why features behave differently across local, staging, and production environments. As a result, developers may accidentally misuse, duplicate, or misconfigure feature flags, increasing debugging time and review complexity.

- Explain how flags are loaded (env vars, build-time config) and where they are defined.
- Provide guidelines for adding new flags and removing old ones.
