   BLOG.HTML — additive stylesheet.
   Loaded AFTER styles.css. Reuses existing tokens (--bg-color, --border,
   --text-main, --text-dim, .cta-card, .cta-btn, .hero-stage, .motto,
   .scroll-reveal-item) and the site's Microsoft-style mouse-proximity glow
   pattern (see ".story-card::before" below, matching nav::before / .card::before
   in styles.css) so the blog never looks like a bolt-on.

/* ---------- HERO / OPENING ----------
   Reuses the site's real ".hero-main-title / .title-line / .blur-char"
   pattern (and its blur-in entrance animation) from styles.css, instead of
   a custom class, so the blog hero matches the homepage/projects/audit
   hero in both type scale and motion — no more feeling like a different,
   smaller page bolted onto the site. */
