Where would you add the font_picker setting for access to Shopify's Font Library?

The font_picker setting is an essential tool that allows theme developers to provide users with access to Shopify's Font Library directly from the theme's customization settings. This capability enhances the user experience by allowing shop owners to pick fonts that align with their brand aesthetics.

The appropriate file for adding the font_picker setting is settings_schema.json. This file is used to define settings that appear in the theme editor. Within this schema, developers can specify various types of input fields, including text fields, color pickers, and the font_picker. By including the font_picker in settings_schema.json, it becomes editable through the theme's customization interface, making it easy for users to select their preferred fonts.

The other files mentioned serve different purposes. For instance, while settings.json is used to store the actual settings values and theme preferences after they have been defined, it does not define settings themselves. The theme_settings.json file is not a standard file in Shopify's structure and doesn't pertain to customization settings. Lastly, font_settings.json is not a recognized configuration file for Shopify themes, further reinforcing that settings_schema.json is the correct choice for adding custom settings like the font_picker.
