   OrangeTree ERP — Design System
   Concept: the accounting ledger, redrawn as a growth ring.
   Every module of the ERP is a ring around one core ledger — General Ledger
   sits at the centre, and Fixed Assets, Petty Cash, SCM, CRM and HCM branch
   outward from it, the way a tree adds a ring for every season it grows.
