Exercise 1: Install & Identify — Possible Solution
====================================================================

STEPS
------------------------------
1. Download and install VS Code from code.visualstudio.com (or via a
   package manager, per the chapter's winget/brew/apt examples).
2. Launch VS Code. You'll land on the Welcome tab.
3. File -> Open Folder... and pick any folder on your machine (an
   existing project folder, or even just your Documents folder).

WHAT TO LOOK FOR IN EACH REGION
------------------------------
Activity Bar (far-left icon strip):
  The topmost icon is the Explorer (usually already selected). Below
  it: Search (magnifying glass), Source Control (branch icon, with a
  small number badge if the folder is a git repo with uncommitted
  changes), Run & Debug (a play button with a bug), and Extensions
  (four squares). One specific thing to note: whether the Source
  Control icon shows a number badge — that alone tells you if the
  folder is a git repo with pending changes.

Side Bar (next to the Activity Bar):
  With Explorer selected, this shows your open folder's file/folder
  tree. One specific thing to note: the folder name in bold at the
  top of the Side Bar — that's your currently open project's root.

Editor Groups (the large central area):
  Empty at first (just the Welcome tab), or showing whichever file
  you've opened from the Explorer. One specific thing to note: the
  tab strip along the top of this area, showing every currently open
  file.

Panel (bottom area, may be collapsed at first):
  Toggle it open via View -> Terminal (or Ctrl+`). One specific thing
  to note: the row of tabs inside it — Terminal, Problems, Output,
  Debug Console — all sharing this one region.

Status Bar (thin strip at the very bottom):
  One specific thing to note: the current git branch name on the
  left (if the folder is a git repo), and the language mode / line
  number on the right, changing based on whichever file is currently
  focused in the Editor Group.

WHY THIS WORKS AS AN ANSWER
------------------------------
Opening a FOLDER rather than a single file (per the chapter's own
"Opening a Folder vs. a File" section) is what makes the Explorer,
Source Control badge, and Status Bar's branch indicator all populate
correctly — a loose single file wouldn't show any of that project-
level context, which is exactly the distinction that section explains.
