Japanese Minimalist Cognitive Lecture Slide With Etching Illustration Prompt

16:9 horizontal pen-and-ink vintage etching illustration for one Japanese minimalist cognitive lecture slide, aesthetic of solitude, existential exploration, and a mysterious unknown abyss. Pure monochrome black and white, extreme high contrast, micro-detail fine linework, layered cross-hatching and stippling, scratchboard texture and paper grain, dramatic chiaroscuro lighting, deep black void as core visual anchor, tiny lone astronaut silhouette against a massive surreal doorway for scale contrast.
Bottom 15-20% is a solid uninterrupted black horizontal bar containing only white Japanese text: centered title in bold Noto Sans JP, "思考の余白"; three left-aligned bullet points "情報を減らす", "問いを残す", "静けさで選ぶ". Designed as slide 1 of a 12-page original cognitive lecture deck. Negative: color, grayscale photo, realistic photography, soft airbrush, blur, low detail, cartoon, anime, watermark, logo, UI elements, extra decoration.
