Vertical Pixel Art Asteroid Field

Create a vertical, retro pixel-style space shooter background in a 9:16 mobile aspect ratio, designed for seamless scrolling. The scene is set in deep outer space, with a deep navy blue to black starry sky background and a wide, empty flight path in the center for gameplay. Two luminous blue nebula streams are added vertically along the left and right edges of the path, punctuated with cyan particles, bright little stars, and occasional twinkling starlight. An asteroid belt is arranged around the path: a total of 34 visible rocky asteroids of varying sizes, irregular and jagged shapes, with dark charcoal gray surfaces and electric blue outlines. The specific layout is as follows: one large, cropped asteroid in the top left corner; one large, cropped asteroid in the center of the left edge; one large asteroid near the bottom left edge; one large, cropped asteroid in the bottom left corner; one large asteroid near the top right edge; one large asteroid in the center of the right edge; one large, cropped asteroid in the bottom right edge; one large asteroid near the bottom right corner; plus 26 smaller asteroids scattered on the left and right sides, while maintaining an open central area. The top right quadrant contains a large, cropped blue asteroid with a glowing atmospheric edge, a visible curved horizon, fine surface texture, and a bright cyan edge light.
