/* ═══ Blog ═══════════════════════════════════════════════════════════════
   Long-form product updates on the marketing site. Reuses site.css tokens and
   shared components (.wrap, .btn, .kicker). Linked ONLY by blog.html and the
   posts under /blog. No site.js dependency — these pages never use the .reveal
   scroll-in classes, so content is always visible even with JS off. */
