How can you access a section file's settings outside of that section?

The correct understanding of accessing a section file's settings lies in recognizing the limitations imposed by Liquid's scope for sections. The choice indicating that you can't access section settings outside of that section underscores the importance of structure and encapsulation within Shopify themes.

In Shopify, each section is designed to encapsulate its settings and variables, which means that the settings specific to a section are not directly accessible from outside that section. This encapsulation is a design choice, allowing for better organization and modularity in theme development. For settings that you want to access globally across different sections or templates, it's recommended to use global settings defined in the theme settings schema instead.

This strict encapsulation ensures sections can be reused and function independently without unintended interference from other parts of the theme. The notion of global settings serves as a workaround for accessing common settings that could be shared across various sections, ensuring that developers maintain clear boundaries between different components of the theme.
