On iOS Safari 17+, the magnetic-button effect on /demos hero stutters at low frame rates. Investigate `requestAnimationFrame` usage and consider gating on `pointer: coarse`.

Repro on my SE — confirmed. We probably need to skip the rAF tick on coarse pointers entirely.

Yeah, I'm gating it on `(pointer: coarse)` and `prefers-reduced-motion`. Pushed to fix/magnetic-ios-perf, PR up shortly.

+1, also let's add a regression test using a small Lighthouse perf budget for /demos hero.
