Challenge 1: Automatically Transitioning a Splash Screen After Two Seconds — Solution Walkthrough

The answer:

Per this chapter's own material, the After Delay trigger accomplishes
this — it fires automatically once a set amount of time passes, with
no user interaction needed at all. Setting the delay to two seconds on
a connection from the splash screen Frame to the main app screen Frame
produces exactly the automatic transition described.

Why the other triggers wouldn't fit this need:

On Click/Tap and On Drag both require the viewer to actually do
something, which contradicts the requirement that no user interaction
is needed. While Hovering requires a cursor positioned over the
element, which doesn't apply to a splash screen a user hasn't
necessarily interacted with at all. Only After Delay fires purely
based on elapsed time.

Why this is a genuinely common real use case:

Per this chapter's own material, After Delay is specifically useful
for simulating a splash screen transitioning on its own — exactly the
scenario described here, where a brief introductory screen
automatically gives way to the real app content after a short pause.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that a time-based, interaction-free transition is
correctly matched to the After Delay trigger, distinguishing it from
the three interaction-based trigger types.
