Pixel / JPEG Placeholder Blur

Raster placeholders (LQIP, BlurHash) are inherently blurry at small sizes. Adding a CSS filter: blur() in the browser smooths visible pixels further, but bleeds surrounding colors into the image edges. Two fixes: set a background color on the container, or zoom the image slightly (transform: scale(1.1)) so the blurred edge overflows the container. Compare both below.
