24-karat gold metallic surface — three-tone spectral gradient: deep amber-brown in shadow recesses, rich warm gold on lit faces, razor-thin champagne-white specular lines where direct light strikes. Single hard key light from upper-left at 45°, casting crisp directional shadows to lower-right. Background: near-black with faint warm amber ambient glow. No colored tints — pure dark void that forces the gold to own all luminosity in the frame. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the 24-karat gold metal, the hard directional key light and the dark void. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as bold 3D-extruded 24-karat gold with deep amber shadow recesses, rich warm gold faces and razor champagne-white speculars. COLOR PRIORITY: keep the font's own colors if specified; otherwise the warm amber-to-champagne gold range on a near-black ground. MARCO rendered as a monumental 24-karat gold dimensional title, occupying the frame with dense sculptural mass and deep extrusion. The metal follows a three-tone spectral finish: deep amber-brown gathers inside bevel recesses, inner corners, and undersides; rich warm gold dominates the illuminated front planes; razor-thin champagne-white mirror speculars trace every exposed edge struck by light. A single hard key light from the upper-left at 45 degrees carves crisp diagonal shadows toward the lower-right, with sharply defined occlusion between letters and beneath the extruded forms. The surrounding field is a pure near-black void, with only a restrained amber atmospheric bloom close to the gold contours; no gray, blue, red, or colored background tints. Subtle airborne gold dust catches isolated points of light near the perimeter, while a barely visible black reflective surface below receives fractured amber reflections and long hard-edged shadow shapes.
