单色 AI 咖啡海报

Goal: Create a dramatic monochrome advertising poster for {argument name="brand name" default="LETZ.AI"}, combining a premium takeaway coffee cup with a visionary AI-growth metaphor.

Canvas: Vertical poster, roughly 4:5 aspect ratio, black-and-white only, high contrast, cinematic lighting, luxury tech brand aesthetic. Use a dark textured tabletop background with a bright overhead spotlight behind the cup and deep shadows.

Layout: Place the brand wordmark in the upper left as “LETZ.AI” in thin wide-spaced uppercase letters, with a small registered mark. On the upper right, show one black takeaway coffee cup with a black plastic lid, lit from behind; the cup front has a large white block letter “L” and small text “LETZ.AI” underneath. The cup casts a long triangular shadow downward into the lower half of the poster. Inside that shadow, reveal a surreal grayscale landscape scene as if projected onto the table: a lone person standing on a rocky cliff, looking toward a futuristic city skyline in the distance, with one rocket launching vertically from the center of the city into cloudy sky and bright sun glow near the horizon.

Main text: On the left side beneath the logo, set a bold condensed uppercase headline in three stacked lines: “FUEL.”, “FOCUS.”, “FORWARD.” Use tall narrow sans-serif type, white or light gray. Below it, add a small spaced uppercase subheading: “AI THAT MOVES AS FAST AS YOU DO.” with a short thin underline accent.

Bottom feature row: Add exactly 3 feature items along the bottom edge, separated by exactly 2 thin vertical divider lines. The 3 items are: 1) lightning-bolt icon with label “REAL-TIME INTELLIGENCE”, 2) crosshair/target icon with label “PRECISION AUTOMATION”, 3) upward diagonal arrow icon with label “UNSTOPPABLE GROWTH”. Keep icons minimal, white line art, small uppercase labels.

Subject details: The scene in the shadow must contain exactly 1 human silhouette, exactly 1 rocket, exactly 1 city skyline, exactly 1 winding river, and mountain silhouettes framing the valley. The coffee cup must be the dominant object and should feel realistic, matte black, with crisp rim highlights and subtle grain.

Visual style: Premium black-and-white commercial photography blended with cinematic matte-painting surrealism, sharp product focus, atmospheric haze, strong chiaroscuro, dramatic triangular composition, inspirational startup/AI advertising mood.

Constraints: Preserve all visible text exactly as specified, avoid additional slogans or extra objects, no color accents, no watermark beyond the brand marks, no clutter, keep the poster clean and editorial.
