Futuristic Electromagnetic Cannon

Create a highly detailed side-view concept art illustration of a futuristic {argument name="weapon type" default="electromagnetic cannon"} floating horizontally against a plain vivid {argument name="background color" default="green chroma key background"}. The cannon should be long and symmetrical, built from dense exposed sci-fi machinery: layered red armor plates, glossy black structural rails, gold/brass rings and brackets, blue glowing coils, cables, pistons, bolts, vents, and small cylindrical modules. Show exactly 3 major sections: a large circular rear power core on the left with red fin-like petals and a bright blue-white energy glow, a long central barrel assembly with 7 prominent golden electromagnetic coil rings surrounding a bright blue plasma beam running through the middle, and a circular front muzzle on the right with red segmented fins, black radial supports, and a blue glowing aperture. Add exactly 2 small landing/support struts beneath the body, one near the rear-left and one near the lower center-right. Use a crisp polished digital painting style with high contrast, clean outlines, comic/anime mecha detailing, metallic reflections, saturated red-gold-blue palette, and no text, people, watermark, smoke, scenery, or shadows beyond subtle object shading. The object should fill most of a 3:2 landscape canvas, centered with generous green empty space around it.
