/*
 * Blog presentation (round 74) - used only by templates/blog.html and
 * templates/blog_post.html. Built on the site's own tokens from
 * style.css (--card, --text, --border, --accent ...), so both themes work
 * with no extra rules. Uses logical properties (inline-start/end) so the
 * same stylesheet serves right-to-left languages (Arabic, Urdu) without a
 * second copy. style.css is deliberately untouched.
