/* ācta insights: the register and the filed article.
   The index is one bond sheet that works as a register book: every post is a
   ledger row, and the categories are folder tabs along the sheet's top edge.
   An article is filed in the guide binder (guide.css loads first on article
   pages). Loads after marketing.css. */
