Minimalist Klein Blue Typography Poster

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 eyebrow_text, then a large stacked headline in black reading main_headline across five tight lines, followed by the final word in vivid Klein blue reading accent_word. Add a tiny tracking-spaced caption beneath the headline reading caption_text. At the very bottom center of the canvas, far below the poster, add a thin vertical black line and tiny uppercase text reading bottom_label. 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.
