/* ============================================================
   CSW Insights — blog archive, single post, search, 404.

   No design export exists for the blog, so this is built from the
   same primitives the three marketing pages use: the paper/ink/violet
   palette, IBM Plex Serif for display, the 1320px twelve-column
   container, 1px hairlines, 2px radii, and the .csw-row hover.

   The one thing it adds is a prose contract (.csw-prose) — long-form
   body copy needs a measure and a vertical rhythm the marketing pages
   never needed.
