"A round football (soccer) shield with a modern 4K design, featuring a black and red color scheme. The shield's border is decorated with small crown details. In the center, there is a fierce panther, symbolizing strength and agility. Around the edges, the text 'Copa Flash Nexus' is prominently displayed, and in the middle, the initials 'NBR' are boldly placed. The overall look should be sleek, modern, and visually striking, with a professional and high-definition style suitable for a contemporary football tournament logo."
