Pixel-perfect 2D normal map shading [now with working images]

Is it possible to have normal map based 2d shading snap to the original pixels? In my case I get smooth shading (bottom image). I would like to maintain the original pixel style (top image).

(edit: added permanent image links)

I found a solution in which the graphics is rendered in low resolution and then displayed in a Sprite using a ViewportTexture. However, I wish there was a less complex solution as I have a lot of independent objects on the screen which all would need an own Viewport.

Not a solution (see here).

Normal map based shading now is pixel perfect: I simply forgot to turn off the texture filtering during import of the normal map (see here).

Getting the original light to align pixel perfectly with the target texture seems to be another matter.
