/* ----------------------------------------------------------------------------
   Steada blog stylesheet.

   Self-contained on purpose: the /blog/* pages are server-rendered by the Go
   control-plane API and fronted by CloudFront, so they cannot reference Astro's
   content-hashed _astro/*.css bundle. This file is served from S3 at the stable
   path /assets/blog.css and mirrors the main site's design tokens and chrome
   (Archivo/Geist, paper + ink + acid) so the blog reads as one brand.
