//! S3.1 conformance — empty-file fixtures from xx.hocon.
//!
//! All ef01-ef06 fixtures parse to the empty object `{}` per HOCON.md §Omit
//! root braces L134-136 (L130-132 is the JSON baseline, not HOCON-normative).
//! Fixture dir: tests/testdata/hocon/empty-file/
//! Expected dir: tests/testdata/expected/empty-file/ — the `-expected.json`
//! sidecars contain `{}` and are normative as-is; the former per-impl
//! override list (assert-error) was revoked 2026-07-23 (xx.hocon E10).
