[gcpm][books] thematic breaks at the top of a page

One effect I noticed in a book recently was the presence of a horizontal 
line indicating a thematic break, but only if the break is at the top of 
a page.  So something like this:

   hr {
     border: none;
     margin: 1em 0;
     padding: 0 5em;
   }

   hr:at-top-of-page {
     border-top: 1px solid black;
   }

When you use an <hr> and it lands at the top of a page, the gap by 
itself won't distinguish itself enough, and that no ink at the top of 
the page is aligned with the text on the following page probably doesn't 
look good.

Maybe :at-top-of-page is too specific; you might want this effect at the 
top of other fragmenting containers, like columns.
