/* ==========================================================================
   SIPL blog — layout and typography.

   Per-client, like layout.php: each client's blog matches that client's site,
   so this is not shared back to the toolkit. It sits alongside
   blog-content.css, which styles the WordPress block markup INSIDE an article
   (.wp-block-*) and nothing else.

   blog-content.css reads --sipl-font-body and --sipl-font-heading. Nothing
   defined them, so every article was falling back to system-ui while the rest
   of the site ran Montserrat and Open Sans. They are defined here.

   Designed text-first on purpose: no post in this blog has a featured image,
   so an image-led card grid would render 130 empty boxes. An editorial list —
   eyebrow, title, excerpt, hairline — reads better and degrades gracefully if
   images appear later (the template already supports them).
