   Field Visit Portal — design tokens
   Palette and type are deliberately ledger/field-notebook inspired:
   ink navy for structure, an amber "verified stamp" accent for the
   moment a visit gets GPS-confirmed, and a monospace face reserved for
   coordinates, IDs and loan numbers — the precise, recorded data.
