/*
  The site header for the hand-built and Airtable-built case study pages.

  These pages are static HTML outside the React app, so they cannot use
  src/components/SiteHeader.jsx. This file and site-header.js reproduce it:
  same links, same Packages dropdown, same mobile menu and floating button.
  Change one, change the other.
