/* ============================================================================
   Tenancy Pilot — blog centre + guide article.

   Layout ported from the prenup-agreement site's blog: a dark hero carrying
   breadcrumb, title and a glass search pill; a 1fr/320px body grid; centred
   editorial cards with a top accent strip and clamped title/excerpt; and, on
   an article, a full-bleed dark masthead over a sticky sidebar holding a
   numbered table of contents.

   Recoloured to this site's strict black/white palette (the source is navy +
   gold) and typeset in Inter/JetBrains Mono rather than Poppins, so it reads
   as one system with the rest of the site.

   Loaded only by templates/blog/*, on top of site.css — it reuses that file's
   tokens, .prose, .eyebrow and .waitlist-form, and scopes every override to a
   blog wrapper so no other page moves.
