//! [`Point`] impl for `Adapt<[T; N]>`.
//!
//! Mirrors `boost/geometry/geometries/adapted/c_array.hpp` (raw C
//! arrays) and `boost/geometry/geometries/adapted/std_array.hpp`
//! (`std::array<T, N>`) collapsed into one impl — Rust's `[T; N]`
//! covers both shapes.
//!
//! # Silent-Cartesian warning
//!
//! This impl pins `type Cs = Cartesian`. A raw `Adapt::<[f64; 2]>(
//! [lon, lat])` therefore satisfies *every* Cartesian-only strategy
//! bound and will silently compute Pythagorean nonsense over
//! lat/lon. Wrap geographic / spherical arrays with
//! [`WithCs`](crate::WithCs) — see [`Adapt`](crate::Adapt)'s
//! rustdoc for the worked example.
