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. Square 1:1. Luxury birthday celebration flatlay — dark velvet surface. 'HAPPY BIRTHDAY' gold 3D text floats as the centrepiece. Around the text: an elegant gold birthday cake with lit candles, scattered gold foil confetti pieces, a champagne flute with bubbles. Candlelight and warm ambient studio light from above. The warm flames echo the amber-brown shadows in the gold letterforms. Premium celebration aesthetic — milestone birthday, luxury party.
