 * Purpose: set archive page to use a saved Beaver Builder template
 * Create a saved BB template using a standard Posts module (change ID below)
 * In the BB posts module, use default query settings (this should override it)

 * Filter the Beaver Builder $query for the posts module on archive pages
 * Note: this filter is here for a convenient view of related functions. 
 * this would typically be in functions.php or a custom plugin.
