/* Variant — "Editor".
   The application is a source file being filled in. Every answer writes a real
   property into application.tsx, and the question itself appears as an inline
   widget wedged into the code where that property will land — the same place
   an editor puts an inline suggestion.

   Code is system monospace; the widget chrome is Inter, because that is exactly
   how a real editor splits them. */
