 /* ============================================================
-   HIDE MATERIAL'S BUILT-IN GLOBE / EXTERNAL-LINK ICON
-   Material injects an inline <svg> globe on every nav link
-   pointing to an external URL — sidebar items AND TOC headings.
-   We already have purpose-built ::before icons for the three
-   Home links (Website, Community, Blog), so suppress the
-   auto-injected globe everywhere else.
+   HIDE MATERIAL'S GLOBE ICON ON EXTERNAL NAV LINKS ONLY
+   Material injects a .md-nav__icon globe SVG on every nav link
+   that opens in a new tab (external URLs). Internal page links
+   have frontmatter icons (icon: material/...) using the same
+   .md-nav__icon structure — we must NOT hide those.
+   Targeting [target="_blank"] isolates only the external links.
