/* =========================================================================
   Invoice Inbox — design tokens
   =========================================================================
   Direction: a small, trustworthy ops console for a live invoice inbox.
   The signature device is the "postmark" — a dashed ring + centre dot,
   standing in for the literal act of a piece of mail being marked as
   received/processed. It appears idle on the PIN card and empty state,
   and animates (breathing / rotating / pulsing) in the header status pill
   to reflect waiting / checking / processing.

   Type: a restrained system serif carries the wordmark and a few section
   labels (ledger-heading feel); system sans carries everything else; a
   system monospace with tabular numerals is used for every figure —
   money, durations, dates, bank details — so the data reads as precise,
   machine-verified figures, ledger-style.

   Colour: cool paper neutrals (not the common warm-cream default) with a
   single postal-ink teal as the interactive/brand accent, kept apart from
   the semantic success/warning/danger hues used for job status.
   No external fonts, no CDN — system stacks only.
