  1.  Urban Geology :  
Input A is a Major City (e.g., {argument name="city" default="Paris"}, New York, Barcelona, Cairo).
Analyze the location to generate   2 Sculptural Assets  :
     The Material (The Stone):  Identify the primary building stone of the region.
         (e.g., Paris -> Beige Lutetian Limestone. NYC -> Grey Concrete/Granite. Petra -> Red Sandstone). 
     The Spire (The Anchor):  Identify the tallest or most recognizable vertical landmark.
         (e.g., The Eiffel Tower, The Empire State Building, Sagrada Familia). 

  2. Relief Map :  
Goal: "Topographic Typography" Macro Photography.
     The Object:  A highly detailed   Bas-Relief Map   carved from a single block of the "Material" (Step 1).
     The Palette:    Monochromatic.   No paint or colors. The image relies entirely on light and shadow to define shapes.

  3. The Typographic Integration  :  
     The Text:  The Name of the City is extruded vertically from the map center in massive, blocky 3D letters.
     The Texture:  The letters are NOT smooth. The   City Grid   continues seamlessly onto the top surface of the letters. Roofs, windows, and streets are carved into the face of the text.
     The Landmark:  The "Spire" (Step 1) stands physically on top of one of the letters, acting as the focal point.

  4.  Syntax  :  
     The Streets:  The roads are carved as deep, sharp grooves into the stone, creating a complex network of shadows.
     The Density:  Extreme high-frequency detail. Thousands of tiny cubes represent the urban sprawl surrounding the text.

  5. Lighting & Atmosphere:  
     Lighting:   Golden Hour.   The sun is low on the horizon, casting long, sharp shadows that reveal the depth of the street carvings and the height of the letters.
     Focus:    Tilt-Shift.   The text/landmark is sharp; the edges of the map blur into a creamy bokeh.

  Output:   ONE image, 1:1 Aspect Ratio, 3D Render, "CNC Carved" aesthetic, High Contrast Texture.
