;; 1. Define Constants
(define-constant CONTRACT-OWNER tx-sender)
(define-constant TOKEN-PRICE u100)

;; 2. Define Data Map (to simulate existing balances)
(define-map balances principal uint)

;; 3. Read-Only Function: Simulate Mint
;; This calculates the "new balance" for a user if they were to mint.
