Two layered sets of SVG rectangles create a woven grid pattern that reveals a central circular window. The first set of horizontal stripes uses an SVG `<mask>` with a white circle to show only the circle’s interior, while the second set of vertical stripes uses an inverted mask to show the area outside the circle. All elements are generated via the DOM API (`document.createElementNS`) without any external libraries. The result is a static, full-window composition of intersecting lines whose contrast defines the circular focal point.
