Static File List

By the end of this guide, you will:

• Define a Model using Data.define to hold your application state

• Understand why state is immutable (Data objects, not instance variables)

• Write an INIT callable that returns your initial model

• Display a static list of example files in your VIEW

• Write your first test using Rooibos::TestHelper

• Use assert_snapshots to verify your VIEW renders correctly

• Understand why tests with static data are fast and reliable

So that I can understand the basic file browser interface

Acceptance Criteria

• Application displays a list of example filenames
