Exercise 3: The Real Cost of Removing the Static Fallback — Possible Solution
====================================================================

Removing the static dashboardSpec fallback would trade away the real,
deliberate UX benefit this chapter specifically calls out - showing
the user something immediately rather than a blank screen while the
real spec streams in. Streaming a response still takes real time, even
if it's fast, and a blank screen during that window reads as the app
being broken or unresponsive rather than genuinely working on the
user's request.

The component would technically be simpler with the fallback removed,
since there'd be one less piece of state and one less spec to manage -
but that simplicity comes directly at the cost of the loading
experience the fallback exists to provide. The static spec doesn't
need to be perfectly relevant to the user's own prompt; its whole job
is just to occupy the screen with something real and dashboard-shaped
until the genuinely personalized version finishes arriving.

ANSWER: Removing the fallback would simplify the component slightly,
but at the real cost of showing users a blank screen during the
streaming window - which reads as the app not working, rather than
genuinely processing the request. The fallback's whole purpose is
occupying that gap with something real, not being a perfectly accurate
preview of the final result.

WHY THIS WORKS AS AN ANSWER
------------------------------
This correctly identifies the genuine tradeoff (a small implementation
simplification against a real, meaningful loss in perceived
responsiveness) rather than treating "simpler" as an unqualified
improvement.
