     · Deep XpertSiM Navy base (#000032) — clean, technical, premium
     · Blue (#0F67CF) as the PRIMARY interactive accent
     · Yellow (#CFA20E) used sparingly as a spark accent only
     · Sky (#85B7E8) soft secondary highlight
     · Subtle line-art "S" watermark + faint diamond lattice — no gold auras
     · Clean borders over heavy glows
     · Funnel Display (headlines) + Lexend (body/buttons)
