//! Native 64-bit floating-point backend.
//!
//! This module provides implementations for standard 64-bit floating-point types:
//! - `f64` for real numbers
//! - `Complex<f64>` for complex numbers
//!
//! ## Submodules
//!
//! - `raw`: Raw trait implementations for `f64` and `Complex<f64>`
//! - `validated`: Validated type aliases and kernel configurations
/// Raw trait implementations for `f64` and `Complex<f64>`.
/// Validated type aliases and kernel configurations for native 64-bit types.
