/* ============================================================================
   Blog — index, article and the landing-page teaser.

   Loaded only by /blogg and /blogg/{slug} (plus the teaser styles, which the
   landing page needs, hence blog.css is linked there too). Everything here
   composes the tokens in theme.css and the scaffolding in home.css — .section,
   .section-head, .section-label, .section-title, .container, .btn-primary,
   .prose — rather than restating them. The design system's rules hold: display
   type is uppercase Barlow Condensed, buttons are 6px and never pill,
   160ms cubic-bezier(.2,.7,.3,1).
