极简克莱因蓝排版海报

Create a minimalist editorial landing-page hero poster on an off-white coated-paper background with subtle dust speckles and scanned paper grain. Center a single vertical rectangular print sheet slightly above the middle of a wide landscape canvas, leaving large empty margins. The sheet has a thin imperfect black ink border with a slightly rough printed texture, plus four small Klein-blue crop/corner registration marks just outside the rectangle, and one small blue circular registration target centered on the top border. Inside the sheet, use stark condensed bold uppercase typography like a printed production document: a tiny tracking-spaced eyebrow at the top reading {argument name="eyebrow text" default="A FILM & AI IMAGE PROMPT WORKBENCH"}, then a large stacked headline in black reading {argument name="main headline" default="SAY THE PICTURE IN YOUR HEAD."} across five tight lines, followed by the final word in vivid Klein blue reading {argument name="accent word" default="CLEARLY."}. Add a tiny tracking-spaced caption beneath the headline reading {argument name="caption text" default="THE PICTURE, PULLED INTO REGISTER."}. At the very bottom center of the canvas, far below the poster, add a thin vertical black line and tiny uppercase text reading {argument name="bottom label" default="SCROLL"}. Use only three colors: warm paper white, black ink, and intense Klein blue. Keep all corners square, no rounded UI elements, no shadows, no gradients, no illustrations, no photos, no extra text.
