/* Bench, option B. One live card travels the page over three surfaces:
   night (the dark bench), mask (soldermask green) and sage (the app's own
   window grey). The card's canvas sits above section backgrounds and below
   their text, so content panels can slide over it.

   Ported from the Bench repo's website/option-b/styles.css for /bench, plus
   the Buy button and terms of sale, which the static page doesn't have. It
   lives in lib/assets, not app/assets, because `stylesheet_link_tag :app`
   links every CSS file under app/assets and the rest of the site must not
   get these global rules. Only layouts/bench.html.erb links it. */
