SmartSecureKeypad

A lightweight, SwiftUI-first secure numeric keypad built as a Swift Package (SPM).
SmartSecureKeypad provides a fixed 3×4 numpad, a PIN indicator, and opt-in shuffle support — while keeping UI rendering fully customizable from the host app.

✅ You build the UI.
✅ The framework handles input buffering (digit/delete), completion, and optional digit shuffling.
✅ Designed to integrate cleanly with real-world apps.
