/* ══════════════════════════════════════════════════════════════════════════
   Blog Index Pages — Latest Trend & Technical Blog
   Extends the existing insights-pages.css component set (.ins-hero,
   .ins-filters, .ins-featured, .ins-card) with thumbnail-image support and a
   page-scoped sub-nav. Purely additive — does not override any selector
   already used by insights.php / insights-*.php, so those pages are
   unaffected. Loaded only on latest-trend.php and technical-blog.php.
