Functions
static void	Deep::linear (float *x, size_t n) noexcept
	Identity activation: f(x) = x. A no-op, kept as a real function so it can be used interchangeably with the other activations through ActivationFn.
static void	Deep::dLinear (float *x, size_t n, bool activated=false) noexcept
	Derivative of linear(): a constant 1 everywhere.
static void	Deep::dLinearInto (float *RESTRICT dst, const float *RESTRICT src, size_t n) noexcept
	Two-buffer variant of dLinear – src is unused (the derivative of a linear function is a constant), kept for signature consistency with To_dFn2's dispatch table.
