/* ---------- Blog (reuses the tokens from styles.css) ----------
   Ported onto the 2026 rebuild's tokens. This file used to read --brand, --border, --radius,
   --radius-sm, --shadow-sm, --shadow-lg and --text-muted, none of which styles.css defines any more;
   an invalid var() invalidates the whole declaration, so every border, radius, shadow and muted
   colour here was being dropped silently. Design language is "Industry": square corners, hairline
   borders, no shadows, Barlow Condensed headings, steel-blue accents. */
