config.env_config

BENGAL_ prefix environment variable overrides (Hugo-style).

Env vars starting with BENGAL_ override config keys.

Underscore = nesting: BENGAL_PARAMS_FOO_BAR → params.foo.bar For keys with underscores, usexas delimiter:

  • BENGALxPARAMSxREPO_URL → params.repo_url
  • BENGALxPARAMSxCOLAB_BRANCH → params.colab_branch
  • BENGALxPARAMSxAPI_KEY → params.api_key

Precedence: BENGAL_ env vars override config file. They run before context inference, so BENGALxPARAMSxREPO_URL takes precedence over GitHub Actions inference.
