Add an abstract image style value for image-set() and parse both the standard and -webkit-prefixed spellings through the existing <image> value path. The parser accepts URL and string image candidates, optional resolution descriptors, and type() filters. Track attr-taint through substituted component values so image-set() candidates using attr()-derived URL-producing tokens are rejected when resolved for URL-using properties. Update the relevant WPT baselines now that image-set() parsing is supported in additional value contexts.
