The :envvar:`OTEL_CONFIG_FILE` environment variable points the SDK at a

sole source for SDK construction. Spec-defined ``OTEL_*`` variables with
schema equivalents are ignored. Env vars may still be read indirectly by
components the file enables (e.g. resource detectors) and via
``${env:VAR}`` substitution inside the file.

Python-implementation extensions outside the spec (``OTEL_PYTHON_*``
variables such as ``OTEL_PYTHON_LOGGING_AUTO_INSTRUMENTATION_ENABLED`` or
:envvar:`OTEL_PYTHON_TRACER_CONFIGURATOR`) are also bypassed when
:envvar:`OTEL_CONFIG_FILE` is set, because the env-var initialisation path
is skipped entirely in favour of the declarative file. Honouring these
alongside a config file is tracked separately.
