std::array< ca_size_t, N >	enlarge_extents (const std::array< ca_size_t, N > &user, const std::size_t halo) noexcept
	Bump the storage extents by `2 * Halo` on every axis.

ca_size_t	positive_mod (ca_index_t v, const ca_size_t n) noexcept
	Wrap a possibly-negative index into `[0, n)` with positive modulo.

ca_size_t	reflect_index (const ca_index_t v, const ca_size_t n) noexcept
	Reflect a signed coordinate into `[0, n)` using the no-repeat triangle wave that also powers `Lattice::at_safe` under `ReflectiveBoundary`.

ca_size_t	clamp_index (const ca_index_t v, const ca_size_t n) noexcept
	Clamp a signed coordinate into `[0, n - 1]` for Neumann fills.
