// This file contains grouped comparison benchmarks.
//
// The compare suite exists to produce stable, human-readable sub-benchmark
// blocks that make it easy to generate focused before/after reports. It does
// not replace the more explicit baseline, path, shape, or parallel files.
// Instead, it groups related strategies under one top-level benchmark name so
// benchmark output is easier to compare and chart.
//
// This file intentionally contains no independent benchmark logic. Every group
// is a thin surface over benchmark bodies defined in the owning benchmark file.

// strategies under one top-level benchmark name.
