/* ============================================================
   TABASSUM — shared design system
   Concept: a bound personal ledger where literature and
   accounting meet. Ink navy + aged parchment + burgundy (respect)
   + brass (money). Ledger rules on numeric pages, lined paper
   on journal pages, tab dividers like a real binder.
