What is the purpose of the "config" folder in a Shopify theme?

The "config" folder in a Shopify theme plays a critical role by storing configuration files that encompass theme settings and customizations. These settings are essential as they allow users to modify various aspects of the theme without needing to edit the code directly. This can include changes to colors, typography, layout preferences, and other customizable options that affect the overall appearance and functionality of the store.

By keeping these configuration files organized within the "config" folder, Shopify ensures that theme developers can provide a user-friendly experience. Users can easily access and modify settings through the Shopify admin, which makes it simpler to personalize their store according to their branding and aesthetic preferences. This centralization of settings promotes efficient management and deployment of theme customizations.

In contrast, the other options do not accurately describe the purpose of the "config" folder. Documentation for theme developers would typically be found in other directories or formats, image files are stored in the "assets" folder, and backend server configurations are not part of the theme’s structure in Shopify. Thus, option B correctly identifies the function of the "config" folder in a Shopify theme.
