/* Shared styling for blog post body content, rendered from the
   blog_posts.content field. Used by both the static build
   (generate-blog-posts.js) and the client-side renderer
   (blog-post.html) so the two rendering paths cannot drift apart. */

/* ── Category colour system ──────────────────────────────────
   Five category colours, reused from existing brand accents
   (Evidence Vault, Correspondence Vault, Atlas, Reports, and the
   Philosophy Statement Builder) rather than inventing new ones.
   Coral (--coral) stays reserved for CTAs and is never assigned
   to a category, so the CTA button always stands out.
   A `.category-*` class is added to a wrapping element
   (article-wrap, post-card, or filter-pill) by generate-blog-posts.js,
   blog.html and blog-post.html, using the category -> class mapping
   in js/category-colors.js, so all three rendering paths agree on
   which class a given category gets. --category-ink is a
   contrast-checked text colour (white or near-black) for use where
   the colour is a solid fill, since a couple of the brand hues are
   too light for reliable white-text contrast (see th rule below). */
