    "prompt": " Studio-style publicity photo of Usain Bolt in a red, superhero-inspired speed suit (no visible DC logos; use generic lightning motifs). He’s in a sprinter’s starting stance on a film soundstage, with a clapperboard in the foreground reading “FLASH REBOOT – TAKE 1.” Bright key light, crisp focus on Bolt, subtle motion blur on his back foot to imply imminent launch. Background: green screen cyc wall and scattered sandbags/c-stands to sell “real production.”"
