This page sets a preference in
localStorage based off
whether a user has opted out of animations (via system settings
like System Preferences / Accessibility / Display / Reduce Motion)
but also via a global toggle.
The toggle will override the initial settings and persist until either the user changes their system settings or interacts with the global toggle.
(Not 100% bulletproof yet, but it's a start)
(Useful for a clean reload for testing initial state)
