   BHAWANI ESTATES (Regd.) — Design System
   Concept: "The Ledger" — a registered property consultancy's visual
   identity built on the brand's own mark (signal blue + vivid orange),
   drafted with the quiet authority of a deed register: hairline rules,
   mono ledger labels, and blueprint corner-marks borrowed from the
   architecture & landscape side of the business.
