Responsive images: the right picture, sharp on every screen

The engine now chooses images the way a mainstream browser does, so photos and graphics load at the correct size and full sharpness. From a set of image sizes a page offers, it picks the one that fits your screen and its pixel density: on a high-resolution Retina display it loads the crisp double-resolution version instead of stretching a smaller one, and on a narrow window it loads a smaller file instead of a needlessly large one. The full picture element is supported, which sites use for two things: art direction, showing a different crop or image at different screen sizes, now follows each source's screen-size condition; and format fallback, where a page offers a modern compact format like AVIF and falls back to JPEG or PNG for browsers that cannot read it, now works correctly, the engine skipping a format it cannot decode and taking the next one it can rather than showing a broken image. The width hint a page gives for each image, including calculated expressions, is read through the same math the rest of the engine uses, so the chosen image matches the real layout. This is a general capability that lifts every image-heavy site; pages without responsive images are unchanged. It moves the overall platform score to 66.
