Switching themes from custom.html

Yep, I meant to come back here and clarify that as well.

Exactly as Gordon suggested, I had to add square brackets [...] around the require("Storage").readJSON("shadowclk.j­son", true) in the Puck.eval() call to wrap the resulting data in an array. Then extract the actual data from the array using let data = dataArray ? dataArray[0] : null;. like this:"

Puck.eval('[require("Storage").readJSON(­"shadowclk.json", true)]', (dataArray) => {
    let data = dataArray ? dataArray[0] : null;
