Prize draw
A campaign page and reward flow for TH true YOGURT.
Customers read the rules, find the code on the card, and continue into the mini app to claim a reward. The draw sits inside that flow, not as an extra banner.

- The campaign page states the dates, how to join, and the prizes.
- The code on the card is the entry, not a loose chat message.
- The path continues into Zalo so the customer can finish on a phone.
