+// A console kept quiet by default. The chatter that helps when something is
+// being chased (the NWC listener's generations, relay health) goes through
+// dlog and shows only once debugging is switched on — from the console with
+// `coinosDebug(true)`, or by opening the app with `?debug=1`. `coinosDebug(false)`
+// turns it off again. Warnings and errors that mean something is wrong are
+// not gated; they stay on console.warn / console.error.
