/* ─────────────────────────────────────────────────────────────
   Top navigation — smooth version.
   Links sit dead-centre in Maria's handwriting font, little hearts
   between them, and a pink squiggle draws itself under the one
   you hover (and stays under the page you're on). The bar slims down
   gently when you scroll. Loaded AFTER each page's own styles.
