Cosmic Spawn Brand Poster

Goal: Create a cinematic vertical brand poster for {argument name="brand name" default="SPAWN"}, set in deep outer space, emphasizing precise layout control and a mystical creator-tool identity. Canvas: Vertical portrait poster, 2:3 aspect ratio, dark black-and-navy starfield background with a faint Milky Way band running vertically through the center. The image should feel spacious, high contrast, and premium. Layout: Place one large abstract white logo in the center, slightly above the midpoint. The logo is composed of exactly 3 discrete white shapes: 1 left semicircle with its flat edge on the right, 1 lower-right semicircle with its flat edge on the left, and 1 four-point sparkle/star shape above and to the right of the semicircles. In the upper-right quadrant, add a stacked slogan in small uppercase serif letters. At the bottom, place the brand name across the width with very wide letter spacing. Text content: Upper-right slogan reads exactly {argument name="slogan text" default="CREATE\nWORLDS\nWITH\nWORDS"}, four centered lines, all caps, elegant serif, pale gray-white, generous tracking. Bottom word reads exactly {argument name="bottom brand text" default="SPAWN"}, five separate capital letters spaced far apart, metallic icy blue-white serif styling with a subtle cyan glow. Visual style: Photorealistic cosmic background with many tiny stars, scattered brighter blue-white stars, faint blue nebula dust, and a subtle vertical galaxy haze. The central logo is flat pure white with crisp edges and no outline. The bottom typography should look dimensional and chrome-like, with beveled highlights, dark inner shading, and a soft electric-blue outer glow. Constraints: Use exactly 2 text areas: the upper-right slogan and the bottom brand word. Keep the composition minimal and centered, with no extra icons, no people, no planets, no borders, no watermark. Preserve a moody sci-fi luxury aesthetic with strong negative space.
