fbentes/zap-deck-app ? reverse-engineered prompt

Build me a native Android app called ZapDeck that helps me scan business cards and save the contact details without typing everything by hand.

I want to take a photo or pick one from the gallery, have the app automatically frame the card, clean up the image, fix rotation, and read the text even offline. Then it should organize the info into a contact, save it locally, and let me send it to WhatsApp, add it to the phone contacts, or share it as a QR code or by NFC.

Please make it feel modern and simple, using a clean Material 3 interface with a smooth scan and review flow, a list of saved cards, and a clear result screen after recognition. If some cards are tricky, use the optional online fallback only when needed. Keep everything private and stored on device by default. If you need to check anything current, look up the latest docs online.
