   Page layout / show-hide state machine

   Whether the hero landing content or the conversation view (header +
   fixed input bar) is showing is driven entirely by Alpine's `started`
   flag on <body> (flipped true the instant a /chat request is fired,
   via htmx:before-request -- not when the response arrives, so the
   transition happens immediately on submit rather than after the
   answer finishes generating). See x-show="!started" / x-show="started"
   in chat.html; [x-cloak] above prevents a flash before Alpine
   initializes. No CSS-only mechanism (`:has()`, sibling combinators)
   is used here -- x-show is the single source of truth for visibility.
