/* Breadcrumb chip
   ----------------
   The little "nathannn.com > page" pill. Self-contained on purpose: it carries
   its own tokens so it can be dropped onto a page that does not load the main
   stylesheet (the sketchbook has its own), and it was previously copy-pasted
   into two stylesheets with four different per-page position overrides.

   Markup:
     <a href="/" class="breadcrumb-link-block">
       <div class="breadcrumb-link-text">nathannn.com</div>
       <div class="breadcrumb-link-arrow">&gt;</div>
       <div class="breadcrumb-link-description">work</div>
     </a>

   The trailing two divs are omitted on the home page, which is the root crumb.
   Add .is-pinned when the chip floats over a full-viewport iframe or canvas
   instead of sitting in the normal flow. */
