Celestial Map Announcement Poster

An elegant mystical astronomy announcement poster with a celestial map motif and gold-on-navy styling. - Canvas & Border: Vertical poster with a deep midnight navy background, subtle paper grain texture, faint stars, and a thin double-line antique gold border with rounded corners. Small compass-star medallions are set into all four corners. - Main Illustration: Slightly above center, a single bright glowing orange-gold starburst emits exactly three luminous gold rays connected to three satellite stars: upper left labeled "[Bedrock]", upper right labeled "[Vertex]", and bottom center labeled "[Foundry]". The bottom star connects via a vertical ray decorated with a small gold rosette sun symbol midway. - Celestial Chart Details: Behind the rays are faint concentric astrolabe rings, radial guide lines, dotted orbital arcs, fine constellation linework, scattered tiny stars, and translucent teal nebula wisps curving around the core. - Typography: In the lower third, a large refined serif title in metallic gold reads "[Auto 模式登陆三大云]". Beneath it, centered in smaller gold serif type, reads "[Claude Code 2.1.157-2.1.158]", followed by a short ornamental divider line with a miniature central star. - Style & Lighting: Antique star atlas meets modern cinematic glow, dark academia aesthetic, luminous gold typography, crisp line art, balanced symmetry, dark uncluttered background without logos or UI.
