## Where to use it
A paper craft tunnel made of nine stacked SVG sheets. Each sheet has a hand cut, wavy opening that gets smaller towards the back, and a drop shadow makes it float above the next one. The layers sway in alternating directions, a warm light glows from the deepest point and a fine grain gives the paper its texture. Lovely for kids' brands, stationery and storytelling pages.
The front sheet takes the first color and the back one the second, with the layers in between mixed evenly. The third color is the light at the end of the tunnel. Moving the pointer shifts each layer by its depth, creating a soft parallax.

I want to add the “Layered paper cut tunnel” block (Backgrounds) from AIMRAN Library to my project.
## What it is
Nine sheets of paper with wavy holes turn slowly and spread apart in depth as the pointer moves across them.
## Chosen settings
- Color 1: #f4e1c1
- Color 2: #c8553d
- Color 3: #ffd27a
- Speed: 1x (from 0.2 to 3x)
- Density / scale: 1x (from 0.5 to 2x)
- Opacity: 1 (from 0.2 to 1)
## What I need
1. Add it to my project with the same look and animation as the reference code: same sizes, colours, radii, shadows, timings and easing.
2. It is built with plain HTML and CSS (the reference wraps it in a React component with its CSS). If my project uses something else (Vue, Svelte, Astro, plain HTML…), translate it without losing any behaviour. If I use Tailwind, turn the styles into classes; if not, keep the CSS in its own file.
3. Expose the settings above as props (or CSS variables) with those values as defaults.
4. Make it work well on phones: nothing that depends only on hover, touch targets of at least 44 px and no overflow on 320 px screens.
5. Make it look right in light and dark mode.
6. Keep it accessible: semantic HTML, roles and aria-* where needed, visible focus and keyboard support.
7. Respect prefers-reduced-motion: with reduced motion, no big animations but the same end result.
