//! S3.1 conformance — empty-file fixtures from xx.hocon.
//!
//! All ef01-ef06 fixtures must produce a parse error per HOCON.md L130.
//! Fixture dir: tests/testdata/hocon/empty-file/
//! Expected dir: tests/testdata/expected/empty-file/ (contains `-expected.json`
//! with `{}` that marks the ground truth; however per the cluster override-list
//! these are known-error fixtures — the impl MUST error for all of them).
//!
//! RED: fails until S3.1 empty-stream guard is implemented.
