Image aspect ratio

The --image-aspect-ratio CSS custom property defines the preferred width-to-height ratio for the image elements in the site. When set to a numeric value, it represents the specific aspect ratio to be set (width divided by height). For example, a value of 1.5 would create a 3:2 ratio where the width is 1.5 times the height. When set to auto, the images will use their intrinsic aspect ratio; however, this could generate alignment issues among images in grid elements if they have different width-to-height ratios from origin.
