   Vault — premium fintech UI
   Minimalism / Swiss style: grid-based, high contrast, restrained colour.
   Dark by default, light on request. Colour is used sparingly and always
   semantically: income, expense, reserve, distribution, payment, outstanding.

   Typeface: IBM Plex Sans (self-hosted — no external request, works offline,
   and keeps the strict `font-src 'self'` CSP intact). IBM Plex Mono carries
   references and identifiers.

   Every text/background pair below was checked to at least 4.5:1.
