Challenge 1: Write a Minimal pyproject.toml — Possible Solution
====================================================================

[build-system]
requires = ["setuptools>=61.0"]
build-backend = "setuptools.build_meta"

[project]
name = "text_utils"
version = "0.1.0"
dependencies = [
    "requests>=2.28.0",
]

WHY THIS WORKS AS AN ANSWER
------------------------------
The [build-system] table reuses this chapter's own example exactly —
requires = ["setuptools>=61.0"] declares what's needed to actually
BUILD the package (setuptools itself, at a minimum compatible
version), and build-backend = "setuptools.build_meta" tells build
tools which specific backend implementation to invoke. This table is
required regardless of which project's data goes in [project] below
it — it's boilerplate every setuptools-based pyproject.toml shares.

The [project] table reuses the chapter's own field names directly:
name = "text_utils" and version = "0.1.0" supply the two pieces of
metadata every package needs, matching exactly what the challenge
specifies.

dependencies = ["requests>=2.28.0"] reuses the chapter's own
dependency-declaration syntax, itself matching the package==version
(here, >=) style from Course 1, Chapter 9's requirements.txt coverage
— just declared inside pyproject.toml's own [project] table instead
of a separate file, which is precisely the modern consolidation this
chapter describes pyproject.toml as providing.

description was intentionally left out here since the challenge didn't
require it — name, version, and dependencies are the minimum fields
actually needed for a working, installable package definition.
