// ! Remember to keep the settings at the end of this file when updating LUX.
//
// The settings are:
//  * `LUX.customerid = 47044334` to let LUX know who this is
//  * `LUX.beaconMode = "simple"` to fire the beacon as an image, which is now
//    allowed by the content security policy.
//  * `LUX.debug = false` turns debugging on and off. Left set to false - and
//    kept in the file so it's easier to remember that this can be turned on.
