信息图 / 教育视觉图 - Celestial Cloud Launch 海报

Goal: Create an elegant mystical astronomy poster announcing {argument name="headline text" default="Auto 模式登陆三大云"} with a celestial map motif and premium gold-on-navy styling.

Canvas: Vertical poster, 2:3 aspect ratio, deep midnight navy background with subtle paper grain, faint stars, and a thin double-line antique gold border with rounded corners. Add small compass-star medallions in all 4 corners.

Main illustration: Center the composition around one bright glowing orange-gold starburst slightly above the middle. From this center, draw exactly 3 luminous gold rays to 3 labeled satellite stars: upper left labeled {argument name="left cloud label" default="Bedrock"}, upper right labeled {argument name="right cloud label" default="Vertex"}, and bottom center labeled {argument name="bottom cloud label" default="Foundry"}. Each satellite point is a smaller radiant star, with the bottom star connected by a vertical ray. Place a small decorative gold rosette/sun symbol on the lower vertical ray between the center and bottom star.

Celestial chart details: Behind the rays, include faint concentric astrolabe rings, radial guide lines, dotted orbital arcs, subtle constellation line drawings, scattered tiny stars, and translucent blue-green nebula wisps curving around the center. The look should feel like an antique star atlas mixed with modern cinematic glow.

Text content: In the lower third, set a large refined serif title in metallic gold: {argument name="headline text" default="Auto 模式登陆三大云"}. Below it, centered in smaller gold serif type, write {argument name="subtitle text" default="Claude Code 2.1.157-2.1.158"}. Under the subtitle, add a short thin ornamental divider line with a tiny diamond/star at its center.

Visual style: Sophisticated, high-end, poetic, celestial, dark academia, occult astronomical chart, luminous gold typography, subtle volumetric glow, balanced symmetry, crisp fine-line ornamentation.

Constraints: Use exactly 3 connected cloud labels and exactly 4 corner medallions. Keep the background dark and uncluttered, preserve the Chinese headline text exactly, avoid logos, people, watermarks, UI elements, or extra captions.
