/* ==========================================================================
   Component: datpro_article
   The reading layout for a single news article. One column, no sidebar, no
   ads, no widgets — the only job of this file is to make CMS-authored prose
   render correctly with zero extra classes.

     .dp-article__masthead   tinted band: breadcrumb · category · h1 · date
     .dp-article__cover      <figure> above the text, one step wider
     .dp-article__notice     muted "this is placeholder content" callout
     .dp-article__body       THE MEASURE — everything typographic lives here
     .dp-article__foot       share row + back link

   MEASURE
   --dp-measure is 47rem (752px) at the 17px body size used here, i.e. roughly
   70–75 characters a line. The container is 1320px; the text deliberately is
   not. Change the token, not the individual rules.

   CMS CONTRACT
   Inside .dp-article__body, plain tags are styled: h2 h3 h4 p ul ol li a
   strong em blockquote figure img figcaption hr table pre code. An editor
   pasting a block of HTML needs no class names at all. Two escape hatches
   exist for content that is intrinsically wide:
     <div class="dp-article__scroll"> … wide table … </div>
     <figure class="dp-article__figure--wide"> … full-measure-plus image … </figure>
