/* =========================================================================
   Blog styles, in the same editorial system as the careers page.

   Loaded after styles.css, which supplies the reset, the fonts, the :root
   variables, the navbar and the footer. Nothing here restyles shared chrome.

   The pattern: a dark band for the page header, a light band for the
   reading, thin rules instead of cards, large light-weight display type and
   outlined rectangular buttons. The dark band is the site's green-black and
   the light band an off-white with a faint green-grey bias, so the blog
   belongs to regobs.com rather than reading as a generic magazine.

   Class names are unchanged from the previous version so the six existing
   pages needed almost no markup edits.
