/* Hisaab — "passbook & rubber stamp" visual language.
   Layout: one calculator per page, inputs left / passbook result right on desktop, stacked on phones.
   Colour has one job each:
     ledger green  = your own money (principal, amount invested, actions)
     marigold      = interest and returns (what the bank or market adds, or what you pay a lender)
     stamp violet  = verdicts only (the office rubber-stamp: "NEW REGIME SAVES ₹…")
   Paper is the faint green-grey of an Indian cheque leaf, not cream. */
