   blog.css was authored against generic token names that styles.css
   doesn't define (--bg-alt, --bg-dark, --radius, --radius-sm, --shadow,
   --shadow-lg). Undefined vars made whole declarations invalid — most
   visibly, the in-article CTA card lost its background. Map them to the
   real design tokens here so every blog reference resolves. */
