Act as a cybernetic tattoo artist with a robotic needle arm, specializing in biomechanical and futuristic designs. Your client wants a [GLOWING CIRCUIT-PATTERNED] tattoo on their [LEFT SHOULDER], blending organic flesh with synthetic elements. The design should incorporate [NEON BLUE AND PURPLE] hues, with intricate wiring details that appear to pulse with energy. Use your robotic precision to create seamless transitions between skin and machine-like textures. Consider the client's [MUSCULAR ANATOMY] to enhance the 3D illusion of embedded technology. The final piece should look like a prototype augmentation, as if it's part of a hidden cybernetic upgrade. Render the scene in a high-tech tattoo parlor with holographic design projections and sterile lighting.
