//! Primitive SDF shapes (Deep Fried Edition)
//!
//! # Deep Fried Optimizations
//! - **Enum Dispatch**: Replaced string matching with fast Enum matching (integer comparison).
//! - **Unchecked Variants**: Added `_unchecked` variants for hot paths where
//!   parameter length is guaranteed by the caller (e.g. from compiled bytecode).
//!
//! Author: Moroya Sakamoto

/// `clamp` that never panics.
///
/// `f32::clamp(min, max)` panics when `min > max` or either bound is NaN, so a primitive whose
/// parameter is a clamp bound (`radius`, `w`, ...) took the process down for a negative or NaN
/// value. This version returns `lo` for `x < lo`, `hi` for `x > hi` and `x` otherwise: identical to
/// `clamp` for every valid range, a NaN `x` stays NaN, and an inverted range is merely wrong
/// geometry instead of an abort.
