/**
 * Premium Learning Article — single blog_post ("مقال تعليمي").
 *
 * A reading-first experience: light lavender hero, reading-progress bar, sticky
 * auto-generated TOC, generously-set Arabic prose, and reusable educational
 * blocks (tip / note / warning / takeaways / summary / …). Scoped under `.nvblog`
 * and built from the same `--b-*` tokens as the archive, so it reads as one system.
 * Loads only on single blog posts (see inc/blog-single.php).
