/* =========================================================================
   Shared premium theme for the connectivity tool family:
     /traceroute  /port-checker  /server-latency-checker
   All three share this one stylesheet and the ".nettool-page" root class so
   the three tools read as one consistent product instead of three
   independently-designed pages. Structure mirrors dns-tools-shared.css
   (hero / search-row / summary-grid / main-grid / panel / data-table), with
   a fresh sky/cyan palette so this family is visually distinct from the
   indigo DNS tools, the teal IP tools and the blue security tools.
