Generate an incredibly detailed 12K mixed media collage forming a human face across the 1128 x 191 px banner. Render each torn paper fragment with ultra-high resolution, showing fine paper fibers, ink bleeds, and subtle creases. The vintage scientific diagrams and mathematical equations should be legible even at extreme zoom levels. Layer meticulously detailed acrylic brushstrokes over this base, with visible paint texture and color mixing. Create the eyes using anatomical drawings so detailed that individual blood vessels are discernible. Form the mouth from a highly detailed word cloud, with each AI-related term crisp and readable. Craft the hair using a combination of intricately woven copper wire sculpture and high-fidelity digital particle effects, where each strand and particle is distinct. Transition the background from a hyper-realistic handmade paper texture to a complex digital gradient. Subtly embed the text "ArtGuru, Professional AI Artist at your service" within the collage elements, using a handwritten-style font with visible ink texture. Apply a precisely controlled glitch art effect and use advanced frequency separation techniques to enhance micro-details while maintaining overall cohesion. Every element should exploit the full potential of 12K resolution.
