   cards.css
   A small, general card system for the org-publish site.

   Two ways to get a card:

   1. On a headline, via a property drawer (what benchmark.css already uses):

        * Some section
        :PROPERTIES:
        :HTML_CONTAINER_CLASS: card
        :END:

   2. On an arbitrary chunk of a page, via an org *special block*.
      ox-html exports any unknown #+begin_NAME block as <div class="NAME">:

        #+begin_card
        anything at all
        #+end_card

      Extra classes go through #+attr_html, and ox-html appends the block
      name to whatever you pass:

        #+attr_html: :class accent-blue
        #+begin_card
        ...
        #+end_card
      -> <div class="accent-blue card">

   Everything below is built from one base (.card) plus modifiers, so the
   benchmark prompt/response/comment colors and a paper header card are the
   same object wearing different accents.
