A wide banner for a streamer channel. The background is dark charcoal with a subtle warm amber gradient. On the left edge, there is a mystical glowing pattern or a mythological symbol (like a bull or rune), placed close to the border. On the right edge, there are soft warm light rays or a gentle glow, also at the very edge. The entire center of the banner is completely empty, dark, and clean — only pure charcoal black, so that platform interface elements remain fully visible. The mood is cozy but intense. 16:9 format.
