Research direction

Start at the BankCardAdapter child-click listener and its notifyItemChanged call, then trace the two convert overloads that handle the payload. Reproduce the rapid tapping case and determine whether the partial update causes the reported ANR; done means rapid clicks no longer freeze the app while the bank-card icon and masked number remain correct.
