/*
  Site top nav (SITE-1450): marketing/templates/top_nav_dark.html, loaded by
  marketing/layout.php and the Learning Center layout after tokens.css.
  Two rows from the 10/20 homepage prototype: logo, AI chat pill and account
  on top (60px), nav links and their dropdowns underneath (44px). Sticky, on
  a see-through scrim. At 768px and below the links row and pill give way to
  a menu button (the same links) and a round "ask" button that opens the
  chat full screen. Total height is
  --ti-nav-h (tokens.css); heroes that slide up under the nav use it too.

  The chat panel is chat.html's markup (#main-chatbot-div), styled here in
  full: MainSite/css/chat.css is not loaded, because its global .hidden and
  .show rules and !important fonts would reach the rest of the page.
