 * Ignition functions and definitions
 *
 * @link    https://developer.wordpress.org/themes/basics/theme-functions/
 * @package Ignition
 * @since   1.0
 *
 * The first file to look at is theme.config.json where you can quickly set up some theme settings
 * like google fonts, icons for various areas and logo position
 * you can also set the mobile menu by editing the mobile_menu_type option to open as app-menu or leave blank to open regular
 * default_acf_header_block: add your post types here to force them to have a header block when a new post is made.
 *
 * Then you should set your CSS variables in variables.scss
 *
 * Once those are both edited, you can come here and add image sizes, widgets and anything else
 * Remember it might not be necessary to enqueue js files here as any js file starting with an underscore will be added automatically to the front end js build
 * That will work only if the file is inside the inc or parts folders.
 * This ability also works for any scss file added with an underscore in those folders too.
 * This also works for underscored php files.
 * therefore all php files in the inc folder are already automatically included
 *
 * Besides adding image sizes, you may find you dont have to do much in here.
