/* =============================================================
   JTA3 SOLUTIONS LLC — STYLESHEET
   Design language: navy / white / light gray / subtle gold.
   Signature motif: the "ledger line" — a thin ruled line with
   a small tick marker, echoing a financial statement entry and
   the idea of one chapter of a business being carried into the
   next. Used sparingly as a structural device throughout.
