一半是皮肤，一半是线框

Frame a vertical 9:16 portrait, tight and centered, the dividing line locked to the exact vertical axis: a single head split precisely down the middle, filling the upper two-thirds of the frame with jaw and shoulders showing in the lower third. On the left, render a lifelike human face — warm-toned skin, subtle pores, short stubble, defined lips, a soft subsurface glow. On the right, reveal a glowing cyan-magenta wireframe mesh, built from thin polygon edges and small illuminated node points tracing the same anatomical contours. Set the background as a dark gradient from deep navy into muted steel gray, filling the top 70%, with generous negative space held open in the lower center for optional typography. Light it with a cool rim light from the right and a warmer key glow from the left, sharpening the material contrast and sculpting crisp shadows along the nose and cheekbones. Keep surface detail precise: matte skin texture with tiny specular highlights on the real half, clean emissive lines with subtle scanline noise and occasional polygonal reflections on the digital half. Hold sharp focus on the eyes and the central split, letting a shallow layering soften the shoulders and background, and render it all as a refined digital painting — controlled brushwork for the skin, vector-like precision for the wireframe.
