Thanks to your addition of a top-level `data-ring-type` attribute and the addition of [this rule](https://github.com/oconnore/gaia/blob/c928f92f72268daf7fc3fbaf75ea4b1e5e5aeee6/apps/clock/style/onring.css#L155-L157):

```css
.ring-display[data-ring-type="timer"] #ring-button-snooze {
  display: none;
}
```

...I think you can remove both this line and [the associated `.hidden` CSS rule](https://github.com/oconnore/gaia/blob/c928f92f72268daf7fc3fbaf75ea4b1e5e5aeee6/apps/clock/style/onring.css#L9-L11).
