/* bl-ads.css - the AdSense boxes (includes/components/ads.php, assets/js/bl-ads.js). Each box has a fixed size,
   chosen from the width of the column it sits in (a container query), and the same before and after the ad loads,
   so nothing on the page moves: 320x100 in a narrow column, 468x60 from 468px, 728x90 from 728px. Google's
   "exact size per width" responsive method, so an ad never grows past its box. The "Advertisement" label sits
   above; the margins keep the box clear of links and buttons. */
