	/**
	 * Detect Divi Builder Activation or Preview Mode
	 *
	 * This utility function checks if the Divi Builder is actively used on the current page
	 * or if it is in preview mode. It determines this through the following conditions:
	 *
	 * 1. **Divi Preview Mode Check:** If Divi is in preview mode (detected via query parameters),
	 *    the function confirms this by validating the `et_pb_preview_nonce` nonce. If verified,
	 *    the function immediately returns `true`, signaling that Divi preview mode is active.
	 *
	 * 2. **Divi Theme Check:** If Divi preview mode is not active, the function checks if the
	 *    Divi theme is the currently active theme. If Divi is active as the main theme, the
	 *    function returns `false`, as there is no need to load builder-specific assets outside
	 *    of preview mode.
	 *
	 * 3. **Divi Builder Plugin Check:** If the Divi theme is not active, the function then checks
	 *    if the Divi Builder plugin is active by looking for the `ET_CORE_VERSION` constant and
	 *    the `_et_pb_use_builder` meta key set to "on" in the current post's metadata. If both
	 *    conditions are met, the function returns `true`, indicating that the Divi Builder plugin
	 *    is active on this page.
