// Recursively stringifies the values of an object, space separated, in an
// SSR safe deterministic way (keys are sorted before stringification)

// ex:
// { b: 3, c: { z: 'zzz', d: null, e: 2 }, d: [10, 12, 11], a: 'one' }
// becomes
// 'one 3 2 zzz 10 12 11'

// `null` and `undefined` values are filtered out
// Dates are converted to their native string format
