CSS and JS 404 On Admin Site Only - New Install
Don't forget AllowOverride All if your Apache is defaulted to AllowOverride None.  The missing directive was prohibiting rewriting from working [properly?] since I had, lastly, moved the rules to .htaccess (where they are in a default installation).  Added it to the "main" &lt;Directory&gt; in my &lt;VirtualHost&gt; and all is well.
