   Ledger360 — Shared Design System / App Shell Theme
   ------------------------------------------------------------
   Every module page includes this ONE stylesheet so the navbar,
   cards, KPI tiles, modals, buttons and charts look and behave
   identically across the whole application. Do not fork this
   file per-module — extend it here and every page picks up the
   change automatically.
