/* The site's chrome (direction B, "warm editorial"): the product nav with its Product menu and phone sheet, the
   practice header used on the consulting pages, and the footer. Namespaced (sc-) so it sits on any page: the homepage
   (home.css), the product pages (landing.css) and the older React pages (legacy-chrome.css). Light, with dark mode
   only where the page itself has one (the homepage adds .sc-auto to <html>). */
