Move the SharedResourceRequest, animation timer, and current frame state out of ImageStyleValue and into a Document-owned table keyed by resolved image URL. ImageStyleValue now keeps only URL metadata and its client list, so image style values no longer need to trace GC edges themselves. Thread the Document through AbstractImageStyleValue APIs that need decoded image data. CSS image fetches snapshot the stylesheet base URL, referrer behavior, and origin-clean state instead of retaining the stylesheet. Remember each client's registered resolved URL when unregistering. This keeps a later document base change from leaving an animated image resource alive. Add text coverage for inline relative image base URLs, stylesheet referrers, imported stylesheet origin-clean behavior, inline @import initiator type, and unregistering an animated background image after a base element change.
