 ⛩️📰 书社 comes with some transforms; namely :⁠—
 
 - **`transforms/asset.xslt`:**
-  Converts `<html:object type="text/css">` elements into corresponding
-    `<html:link rel="stylesheet">` elements and
-    `<html:object type="text/javascript">` elements into corresponding
-    `<html:script>` elements.
-  This transform enables embedding of `text/css` and `text/javascript`
-    files, which ordinarily are considered assets (as they lack
-    associated parsers).
+  Converts `<html:object>` elements which correspond to recognized
+    media types into the appropriate H·T·M·L elements, and deletes
+    `<html:style>` elements from the body of the document and moves
+    them to the head.
