/* Back to Top button — sitewide (Base Outline asset row)
   Added 2026-10-20 for SOL-30797.
   Button is injected by /images/pub/back-to-top.js and only shown after scrolling.
   Colours from content/override.css: primary navy #32385A, link blue #0722CE.
   Icon is an inline SVG so no icon font is involved (Font Awesome CDN must not be loaded on this site). */
