/* ==========================================================================
   PayTrack — design tokens
   Concept: a payroll ledger rebuilt as a terminal. Deep charcoal-navy base,
   amber for "ink" (positive/primary values), cyan for live/data states,
   red for deductions. Numbers always render in monospace, like a punch-card
   or calculator display — headers stay geometric/humanist to keep the UI
   from feeling like a raw terminal emulator.
