KOKKOS_INLINE_FUNCTION scalar	NeoN::dsl::copySign (const scalar mag, const scalar s)
	Returns |mag| carrying the sign of s (scalar overload).
KOKKOS_INLINE_FUNCTION scalar	NeoN::dsl::componentCopySign (const scalar mag, const scalar s)
	Componentwise sign-copy (scalar overload).
KOKKOS_INLINE_FUNCTION Vec3	NeoN::dsl::componentCopySign (const Vec3 &mag, const Vec3 &s)
	Componentwise sign-copy (Vec3 overload — all 3 components).
KOKKOS_INLINE_FUNCTION scalar	NeoN::dsl::componentMag (const scalar value)
	Componentwise magnitude (scalar overload).
KOKKOS_INLINE_FUNCTION Vec3	NeoN::dsl::componentMag (const Vec3 &value)
	Componentwise magnitude (Vec3 overload — keeps all 3 components, does NOT collapse to the L2 norm that the global mag(Vec3) returns).
KOKKOS_INLINE_FUNCTION scalar	NeoN::dsl::componentMax (const scalar lhs, const scalar rhs)
	Componentwise max (scalar overload).
KOKKOS_INLINE_FUNCTION Vec3	NeoN::dsl::componentMax (const Vec3 &lhs, const Vec3 &rhs)
	Componentwise max (Vec3 overload — per component).
