  Buffer v3 blog index, topic and author pages (/blog). A port of the index
  parts of the v1 buffer-blog.css with the v3 values from
  design/v3-handoff/Buffer Blog v3.dc.html and Blog Card v3.dc.html.
  As on v1, the design's container queries are viewport media queries at
  the same widths (cqw becomes vw). Breakpoints: >= 1024 · 768–1023 · < 768.

  Tokens, nav, footer, buttons, tactile press states, segmented controls and
  the glows come from v3-site.css.
