/**
 * Caches the parsed version of the specified CSS snippet. We key the cache based on CSS snippets (rather
 * than requests and responses as is done above) because a) this allows us to cache inline CSS, b) CSS is
 * extremely expensive to parse, so we want to avoid it as much as possible, c) CSS files aren't usually
 * nearly as large as JavaScript files, so memory bloat won't be too bad, and d) caching on requests and
 * responses requires checking dynamicity (see {@link #isCacheableContent(WebResponse)}), and headers often
 * aren't set up correctly, disallowing caching when in fact it should be allowed.
 *
 * @param css the CSS snippet from which <tt>styleSheet</tt> is derived
 * @param styleSheet the parsed version of <tt>css</tt>
