Ultra-luxurious dark law firm hero background. Deep near-black (#0a0a0a) backdrop with subtle abstract gold texture — faint gold linear light streaks and a whisper of geometric pattern, cinematic and moody. Suggestion of polished dark marble with fine gold veining. Elegant, prestigious, authoritative, sophisticated. No text, no people, no logos. Minimalist high-end negative space with soft gold glow in corners.
