 *   `{{ ... }}`: Used for **expressions**. This is where you put variables you want to display, or even simple calculations or function calls. The result is inserted into the HTML.
 *   `{% ... %}`: Used for **statements**. This includes things like `if`/`else` blocks, `for` loops, and other control structures. These don't directly output text but control how the template is rendered.

 **Explanation:**

 *   `{% if user and user.is_logged_in %}`: Starts an `if` block. Jinja2 checks if the `user` variable exists and if its `is_logged_in` attribute is true.
 *   `{% else %}`: If the `if` condition is false, the code under `else` is used.
 *   `{% endif %}`: Marks the end of the `if` block.
 *   `{{ user.name }}`: Accesses the `name` attribute of the `user` dictionary passed from Python.

 If you run this and visit `/profile`, you'll see the "Welcome back, Charlie!" message. If you change `current_user` to `None` in the Python code and refresh, you'll see the "Welcome, Guest!" message.

 Using `url_for` in templates ensures that your links will always point to the correct place, even if you change the URL rules in your Python code later.
