Added promo codes and deeplinks. The plan is to put a “Try Trial” button on the website that deep-links straight into the app and auto-claims free traffic. To stop bots from abusing this, hooked up Abuse Shield with silent guest auth across our Axum backend and KMP client. Android uses ANDROID_ID, while iOS and macOS generate a persistent 256-bit key in Keychain to authenticate devices without login screens. It’s still a fairly basic check for now, but better than nothing. The rest was UI cleanup.
