"prompt": "A cinematic NASA space mission poster, 2:3 portrait format, pure black background.\n\nA single astronaut in strict side profile facing left, wearing a NASA orange-red Orion pressure suit with mission patches and a NASA logo badge on the chest. Full helmet with clear visor and headset microphone. Cold white rim light from the left creates a sharp specular highlight along the helmet edge and left cheekbone. Deep shadows on the right side of the face. Ultra-high contrast, near-monochromatic color grade — the red suit is the only color accent.\n\nA large crescent moon occupies the upper-center background, photorealistic lunar surface with visible craters, slightly soft focus.\n\nThe lower 45% of the image fades to pure black through a seamless gradient veil, creating a clean dark area for the poster typography.\n\nPoster typography, all text white, all uppercase, Helvetica Neue style:\n\n- Centered at 67% down: lightweight tracked text reading exactly \"10 DAYS | 685,000 MILES\", letter-spacing very wide, font-size small, opacity 85%\n- Centered just below: even lighter text reading exactly \"AROUND THE MOON FOR ALL HUMANITY\", font-size smaller, opacity 70%\n- Centered at 78% down: the main title in very large condensed bold font reading exactly \"ARTEMIS II\", extreme letter-spacing, white, dominant visual element\n- A thin horizontal white line spanning the width at 84% down, opacity 30%\n- Centered at 88% down: bold tracked uppercase text reading exactly \"ELON MUSK\", font-size medium-large\n- Centered just below the name: thin lightweight text reading exactly \"MISSION SPECIALIST\", very wide letter-spacing, opacity 55%\n\nTop-right corner: NASA logo and ARTEMIS mission badge in white, small size, opacity 90%.\n\nEditorial poster photography, studio lighting, 4K resolution.",
