nanobanana prompt: Architectural Evolution Diorama with Hyper-realistic 3D Timeline

Input Variable A:  [libraries] (e.g., Skyscrapers, Bridges, Libraries, Prisons)Input Variable B:  [6] (e.g., 3, 5, or 8)  System Instruction:  Generate a hyper-realistic, 3D "Timeline Diorama" visualizing the evolution of an Architectural Typology.  1.  Chronology Calculation:        Analyze Input B (The Count):   You must generate exactly [Input B] distinct structures.      The Timeline Math:   Divide human history (5000 BC to 2100 AD) into [Input B] equal milestones.         Example (If Input B = 4):  Ancient -> Medieval -> Industrial -> Future.         Example (If Input B = 6):  Ancient -> Classical -> Gothic -> Industrial -> Modernist -> Future.      The Selection:   For each Calculated Era, identify the most iconic architectural style for [Input A].  2.  Container (The Infinite Slab):        The Platform:   A long, continuous   Museum Display Plinth   (Marble or Concrete) extending diagonally into the distance.      The Divider:   Subtle "fissures" or light strips in the floor separate the eras.  3.  Content Generation (The Evolution):    CRITICAL:   Generate a distinct structure for each calculation in Step 1.      Era [N] (The Style):   Construct the building using materials strictly available in that time period.         Ancient:  Mud, Thatch, Rough Stone.         Classical/Medieval:  Marble, Wood beams, Stained Glass.         Industrial:  Red Brick, Iron, Soot.         Modern:  Concrete, Steel, Plate Glass.         Future:  Bioplastic, Aerogel, Holograms, Greenery.  4.  Label :      In front of each building, place a   Physical 3D Date Label   made of the era's dominant material.         (e.g., "1920" made of Art Deco Gold; "2050" made of glowing blue Hologram).   5. Visual Syntax:        Camera:   Isometric or High-Angle Diagonal to fit all [Input B] items in one frame.      Scale:   Uniform scale. 1:100 Architectural Model style.      Atmosphere:   The lighting evolves across the image (Sunrise on the left -> Noon -> Sunset -> Neon Night on the right).  Output:   ONE image, Ultra-Wide Aspect Ratio (21:9 if eras > 4), Architectural Render, Museum Lighting, High Texture Fidelity.
