赛博肖像：PCB与瓷器分裂

Front-facing cybernetic portrait, perfect vertical bisect. LEFT HALF: matte black FR-4 PCB skin with copper traces (~0.15 mm), SMD chips (QFN/BGA mix), fine silkscreen, micro-solder dots, subtle anisotropic speculars. RIGHT HALF: porcelain-white facial shell with faint micro-pitting, clean seams, intact eyelashes and brows. Eyes centered, teal irises, glossy wetline. Studio product lighting: soft 3/4 key + cool back rim, low internal haze to reveal specular roll-off; no bloom. Lens feel 100mm, minimal distortion, symmetric crop, ultra-clean edges; hyperreal CGI finish. Negative prompt: blurry, oversharpened grain, extra seams on lips or nostrils, random wires sticking out, text/logos on face, heavy bloom, moiré, banding, watermark
