/* =========================================================================
   SINYAL MOTORU — "Ölçüm Cihazı" tasarım sistemi
   =========================================================================
   Konsept: bu bir fintech panosu değil, bir BILIMSEL ALET okumasıdır.
   Osiloskop, sismograf, spektrometre. Wyckoff'un özü gürültünün içindeki
   gizli faaliyetin izini okumaktır; arayüz de bir iz okuyucu gibi davranır.

   Ürünün karakteri dürüstlük: "tahmin değil, tanımlama". Bu yüzden hiçbir
   şey abartılmaz — parlak yeşil "AL" rozetleri yok, ölçüm var.
