/* =====================================================
   DESIGN TOKENS
   "Claim Ledger" system — grounded in the artifacts of
   medical billing itself: the superbill, the EOB line
   item, the approved/denied stamp. Ink-navy authority,
   cool ledger-paper background, clay for the problem
   (denials), teal for the resolution (paid claims).
   Edit these once to re-theme the whole site.
