The dealer's turn

What we are doing

The dealer has no choices: below 17 they draw, at 17 or more they stand, and then the round is finished. To make it feel like a real table, each of the dealer's moves waits half a second (30 frames).

```js
const DELAY = 30 // frames between the dealer's cards
let timer

  timer = DELAY

function update() {
  if (phase !== 'dealer') return
  timer -= 1
  if (timer > 0) return
  // The dealer has no choice: draw below 17, stand on 17 or more.
  if (handValue(dealer) < 17) {
    dealer.push(nextCard())
    timer = DELAY
  } else finish()
}

  update()
```

What it means

timer counts down frames; the dealer acts only when it reaches 0.
After a card the timer starts again, so the cards come one by one.
When the dealer stands, finish compares and pays.

Your turn

Under BET, write DELAY; under bet, write timer; in stand, set the timer.
Above press, write update.
In loop, call update() before draw().
