Dreamy 3D Paper Cut Light Box

Generate an artistic photography image of the 【3D Paper Cut Light Box】 with a dreamy and three-dimensional feel.  
The theme of the paper sculpture is: [{argument name="theme" default="forest deer under the moonlight"}].

1. Layered Structure and Composition (Layering Logic):
Design the image as a real paper sculpture lightbox, which must be composed of **5–7 layers of paper** stacked together, each layer with its own depth of field and clear outline, and you can see the thickness of the paper and the shadows between layers.

1. Core Structure:
- The image presents a clear **Multi-layered Silhouette** effect, with visible physical spacing between paper layers.
- The overall composition is vertical 3:4, with the lightbox centered and a small amount of space left at the edges of the frame, resembling a luminous art installation placed on a tabletop.

2. Depth of field layout:
- Foreground (Layers 1–2): Use dark, detailed silhouette structures to form framed scenes at the edges of the frame.  
  Elements must match the current theme, for example:  
  · Forest / Nature themes: branches, vines, leaf outlines;  
  · City/castle themes: window frames, arches, bridges, railings, steel structures;  
  · Undersea / Fantasy themes: rock arches, coral, wreckage outlines, etc.
- Middle Shot (Floors 3–4): The **core subject** of this theme, located near the center of the center of the frame, occupying the main visual proportion.  
  The main contour must be clear and complete, and must not be excessively obscured by foreground structures.
- Foreground (5th–6th layers): Use more simplified, weaker silhouettes to depict distant environments and background structures, providing spatial depth to the frame.

3. Three-dimensionality:
- There should be clear physical spacing and shadows between layers. Light creates a gentle gradient of light and shadow between the layers, highlighting the thickness and 3D depth of the paper, making the image look like a real paper sculpture lightbox rather than a flat illustration.

2. Light and Atmosphere (Backlighting Magic):
1. Backlighting:
- The light source must come from the **deepest part / very end** of the image, penetrating all layers of paper from the background forward.  
- Light passes through the hollows of each layer of paper, creating soft, volumetric light and brightness that gradually fades from far to near.

2. Color gradient (adaptive color scheme based on theme):
If no specific color theme is specified, automatically select the main color and gradient scheme that match the current paper sculpture's theme, and always maintain a soft overall impression suitable for viewing as a "night light." The example logic is as follows (for reference only):

- If the theme leans toward **forest / nature / fairy tale**:  
  · Uses gradients of [Warm Gold / Soft Moonlight → Cool Blue / Dark Green],  
  · Create the feeling of moonlight passing through the woods and fireflies lighting up the treetops.
- If the theme leans toward **Undersea / Deep Sea / Ships / Coral**:  
  · Uses cool gradients of [teal / blue-green → deep blue / indigo],  
  · The light source seems to shine from the surface of the water or the core of deep-sea energy, giving it a hint of glowing plankton.
- If the theme leans toward **winter / snow / polar / ice crystals**:  
  · It features a cool gradient in [Ice Blue / Cool White → Light Purple / Dark Blue],  
  · It has a quiet texture with reflections from snowy nights and ice crystal refractions.
- If the theme leans toward **Cyber City / City Night View / Neon Streets**:  
  · It features a contrasting gradient of [Dusk Amber Gold / Orange → Electric Blue / Indigo],  
  · Accent buildings and signboards with a touch of blue, purple, and pink neon, but keep them soft and not glaring.
- If the theme leans toward **castle / medieval town / candlelight scene**:  
  · Featuring gradients in [Candlelight Gold / Warm Orange → Indigo / Deep Purple Night Sky],  
  · It was as if the windows of a distant castle had just lit up.
- If the theme leans toward **Starry Sky / Universe / Space Travel**:  
  · Uses cosmic gradients in [Deep Blue / Indigo → Purple / Slightly Golden Halo],  
  · Starlight and nebulae glow softly with golden or bluish-purple hues.

If users clearly specify color direction or atmosphere in the theme (for example, "cool sci-fi feeling," "powder blue dreamy series," or "black gold mystery"),  
User color is given the highest priority, while maintaining the soft backlight effect and healing atmosphere of the paper sculpture lightbox.

3. Overall Impression:
- The visuals should be filled with tranquility, healing, and a fairy-tale feeling, like a softly glowing bedtime story lightbox,  
  Instead of noisy, glaring neon posters or infographic styles.

3. Material & Details:
1. Paper texture:
- Emphasize the authentic texture of **high-grammetry art paper**:  
  · The paper surface has fine textures and faintly visible paper fibers;  
  · Cut edges are clean and sharp, with clear thickness at the edges of the paper layer;  
  · When light passes through, it creates a soft diffuse reflection and weak translucency, rather than a plastic or metallic texture.

2. Physical Lightbox Photography Experience:
- The image must be presented as a **photographic work of a physical lightbox**, rather than a flat illustration or digital vector style.  
- The framed structure of the lightbox (such as a simple white or light wood frame) can be faintly seen, as well as slightly blurred tabletops or placement environments.  
- Overall natural lighting with a realistic depth effect: the foreground is slightly blurred, the middle subject is clear, and the background is soft.

3. Detail decoration:
- A small number of tiny, floating dotted elements can be dotted between the layers of paper to enhance the sense of space, for example:  
  · A faint glow like stars;  
  · Fine dust particles;  
  · Snowflakes, bubbles, or tiny light dots related to the theme.  
- Quantity must be restrained, serving only as a decorative touch for atmosphere and space. It must not disrupt the overall silhouette structure or layering, nor make the composition cluttered.
