//! Full Benchmark Suite for `solidcv` vs. OpenCV 5.0.0 & Dense VLM/SAE/3D Baselines.
//!
//! ## Benchmark Methodology Notes
//! 1. **Zero-FFI Reference Constants for OpenCV 5.0.0 (Stages 1-5, 8, 13)**:
//!    `solidcv` has zero C++ dependencies so `cargo run --release --example full_suite_benchmark`
//!    compiles and runs out of the box without requiring a local C++ `libopencv` 5.0 installation.
//!    The `opencv5_s*_us` reference numbers are pre-recorded `libopencv` 5.0.0 (`arm64` NEON /
//!    Apple Accelerate) timings captured on the same Apple Silicon reference host.
//! 2. **Separation of Direct OpenCV Kernels vs. Algorithmic / Complexity-Class Baselines**:
//!    Stages 1-5, 8, and 13 compare 1-to-1 against OpenCV 5.0.0 C++ operators.
//!    Stages 6, 7, 9-12, and 14-16 benchmark `solidcv`'s sub-linear / bit-sliced operators
//!    (3D Zobrist octrees, `(3+1)D` dyadic ray squaring, ViT patch-token pruning, and 1-bit
//!    `b1.xor.popc` SAE matching) against the dense $O(N)$ loops they replace. Both subset
//!    geometric means and the combined geometric mean are reported separately at the end.
//!
//! Run with:
//! ```bash
//! cargo run --release --example full_suite_benchmark
//! ```
