A parallelogram is a shifted rectangle whose opposite sides stay parallel. It adds direction to a slanted label or a speed-inspired background panel.
`width` and `height` are half-sizes, each from 0.02 to 1. `skew` tilts the top edge horizontally from -0.4 to 0.4, while `rotation` turns the whole shape from 0 to 360 degrees.
`skew` changes one edge's slant, while `rotation` turns the entire shape. Place it beside `Trapezoid` to compare slant with changing edge widths, and check the slanted edge and text spacing when using it behind a label.
When to use
Use it for slanted labels, banners, or speed-inspired panels. It creates a directional surface compared with a rectangle. Avoid it when the top and bottom widths must differ or when a card needs vertical alignment.
