 /**
  * Single typed preference: a value that has a current snapshot, observable changes, and a
  * setter. "Cleared" / "absent" is represented in the value type itself (e.g. `Pref<UserId?>`
  * with `null` for "no current user", `Pref<Boolean>` with `false` for unset flags) so the
  * interface stays minimal — no `clear()` ceremony at the call sites.
