Nano Banana 2.1 Op Art Moire Engraving Grid

2x2 grid, 16:9. Op-art moire engraved contour illusion. Four subjects emerge only through deformation of continuous black lines on white: a human eye, a sunflower, a vinyl record, and a cat face. High line density, black on white, radial concentric wave vortex contour hybrid fields. No conventional outlines where possible, no gray fills, no shading except line-frequency shading, crisp monochrome vector-like marks, no text, no watermark.
