YouTube channel banner for a channel named 'Тайный код' (Secret Code). The atmosphere should be one of mystery and ancient riddles. Imagine an old parchment background where glowing, modern digital or neon symbols appear. In the center, a mysterious stylized logo combining an all-seeing eye and a key. The overall aesthetic should be dark, intriguing, and professional. The text 'Тайный код' should be clearly visible in a unique, slightly cryptic font. Cinematic quality, high detail.
