/* ============================================================
   Prize-Linked Savings Platform — shared styles
   Design intent: this is back-office infrastructure for banks,
   not a consumer lottery surface. Calm, legible, numerate.
   Navy/slate base, a single warm gold accent reserved for prize
   and winner moments only — everything else stays quiet so that
   accent actually means something when it appears.
