Amber v6.2.0 rejects a plain nostrsigner: navigation as malformed: it reads the signer parameters from intent extras, which a window.location navigation cannot set. An intent:// URL lets the launcher pass the event as the data URI plus type/returnType/appName/callbackUrl as S.* extras, so Amber accepts the request and shows its sign dialog. The query is also kept on the data URI for the EXTRA_APPLICATION_ID web flow. Note: on the emulator with Amber v6.2.0 the post-approval callback did not always fire (Amber returns via setResult when callingPackage != null); needs verification on a real device.
