//! Golden-fixture tests over a real DDR5 SPD image.
//!
//! The fixture is a real, published 1024-byte DDR5 SPD dump (see
//! `docs/validated-against.md`); it is treated as opaque input. The snapshot
//! locks the decode against regressions. It does not by itself prove the decode
//! is correct: correctness is verified at review against an independent decoder
//! and the part datasheet.
