Mike Conley 960d5e2248 Bug 2041814 - Add an opacity hover effect for variations when not animating. r=home-newtab-reviewers,thecount Per UX, we want a hint that there's an interaction here, so the idea is to adjust opacity to 0.8 if the mouse is hovering one of the variations, except when: 1. prefers-reduce-motion is set to reduce, and 2. The animation is underway Differential Revision: https://phabricator.services.mozilla.com/D302370		2026-05-26 02:40:20 +00:00
