Exercise 1: Running the Server With No Build Step — Possible Solution
====================================================================

COMMAND
------------------------------
node server.js

CONFIRMATION
------------------------------
The server starts immediately - no npm run build, no compiled output
directory, no transpilation step of any kind. Visiting
http://localhost:3000 serves the full site: the catch-all routing
from Chapter 3, the database-backed pages from Chapter 6, and the
admin endpoints from later chapters, all running directly from the
same source files written throughout the course.

WHY THIS WORKS AS AN ANSWER
------------------------------
It correctly runs the single command required, and correctly confirms
the site is fully functional with no build artifact ever produced or
needed - concrete proof of the chapter's own claim that this is the
most minimal deployment story in the series.
