Bold typographic poster prompt

Design a finished poster in portrait format. Headline: "Summer Jazz Night". Subtitle: "Live on the rooftop". Include these details as legible text: Friday, July 12 · 8 pm · Harbor Hall Visual style: Bold typographic. Colors: midnight blue and gold. Visual direction: a saxophone silhouette against a full moon over a city skyline Clear typographic hierarchy. Spell all text exactly as given and add no other text. The poster fills the whole image edge to edge: no mockup, frame, wall or surrounding scene. large condensed sans-serif type dominates the layout, high contrast, tight grid, the image is secondary to the words Generous negative space. Warm off-white paper with subtle fibers and grain. Limit the palette to the colors named and the paper, nothing else. No watermark, no logo, no signature, no border. AVOID: no digital gradients, no glossy 3D, no photoreal background, no clip-art look, no cheap retro filter, no template feel, no text beyond what is specified
