Native channel samples

Each channel retains its source wavelength grid and values. The plot uses shared display axes; gaps and negative values remain visible. No normalization, interpolation, averaging, or resampling is applied.

Native samples on a shared display axis: 380–780 nm, -0.006057666 to 0.98847586. Curves are not normalized, averaged, interpolated, or resampled.
