 * `hidden` has to be said again here, because `display` above already beat it.

 * so `display: inline-flex` won and the Google Play badge kept rendering at
 * full size with the attribute sitting on it. Caught 2026-09-19 by screenshotting
 * the page rather than reading the markup: the fix that added `hidden` changed
