(See attached screenshots for images of the following text fragments.)

For a type element, annotations are displayed as part of the "signature" block, in text like this:

type-description.png
--------------------
Module m
Package p
Class C

java.lang.Object
p.C
@Anno
public class C
extends java.lang.Object
This is a class.
--------------------

However, for a module or package, there is currently no equivalent "signature block", and so the annotations get pushed up into the header (i.e. the <div> immediately below the top navbar, like this:

module-description.png
--------------------
@Anno

Module m

This is a module.
--------------------

package-description.png
--------------------
Module m
@Anno

Package p

This is a package.
--------------------

This definitely looks "weird" and the annotation looks out of place.

A better solution would be to introduce an analogous signature block, similar to that provided on type declaration pages.

This would also help regularize the structure between the pages for module/package/type declaration pages.
