/* FlightBeat calculator component styles.
   Shared by the calculator page (/calculator) and the homepage hero, so the
   live calculator looks identical in both places. Tokens, fonts, and the base
   body live here too. Nav and footer come from chrome.css; the homepage adds a
   small inline block for its landing sections (hero copy, routes, facts). */
