Present a clear, 45° top-down isometric miniature 3D cartoon scene of the historical event “EVENT”, featuring its most iconic moment: [DESCRIPTION]. Use soft refined textures, realistic PBR materials, and gentle lifelike lighting. Create a small raised diorama-style base that includes the most recognizable elements of this moment, along with tiny stylized characters if needed (no facial details). Use a clean solid [BACKGROUND COLOR] background. At the top-center, display “EVENT” in large bold text, directly beneath it show a short descriptive subtitle in medium text, and place a small official symbol or simplified icon below the subtitle. All text must automatically match the background contrast (white or black). Composition: perfectly centered layout, square 1080x1080, ultra-clean, high-clarity diorama aesthetic.
