I ran into this exact problem recently while using fox.php. I ended up
modifying it to search for its .css files like this:

// Search path for fox.css files, if any.
SDV
  ( $FoxPubListFmt
  , array
      ( 'pub/css/fox/fox.css'        => '$PubDirUrl/css/fox/fox.css'
      , '$FarmD/pub/css/fox/fox.css' => '$FarmPubDirUrl/css/fox/fox.css'
      )
  );

# load special styles for delete button and links and for message classes
foreach((array)$FoxPubListFmt as $k=>$v)
  if (file_exists(FmtPageName($k,$pagename)))
    $HTMLHeaderFmt['fox'][] =
      "<link rel='stylesheet' type='text/css' href='$v' media='screen' />\n";
