How far into the round?

What we are doing

To make the game harder as it goes, we first need a number for how far the round is: 0 at the start, 1 at the end.

```js
// 0 when the round starts, 1 when it ends.
function progress() {
  return Math.min(1, Math.max(0, 1 - (endsAt - now) / ROUND))
}
```

What it means

• (endsAt - now) / ROUND is the part of the round still left: 1 at the start, 0 at the end. One minus it is the part done.
• Math.max(0, ...) and Math.min(1, ...) keep the answer between 0 and 1, even before or after the round.
