How does KasVault calculate the transaction fee when sending KAS?

KasVault calculates the transaction fee automatically once you fill in both the recipient address and the amount you want to send. When you type the destination address into the "Send to Address" field and enter a KAS amount in the "Amount in KAS" field, the wallet computes the fee for you — you do not need to set it manually. This matters for beginners because it removes guesswork: you can see exactly what you will pay before confirming, so there are no surprises when the transaction goes out.
