fix(mobile): scope desktop scroll CSS to pointer:fine + guard reactive-glow scroll listener — v1.1.3

[Copilot]

Three unconditional behaviours were causing mobile scroll lag: overscroll-behavior-y: contain kills iOS rubber-band/momentum, scroll-behavior: smooth globally fights native momentum scroll, and the reactive-glow.js scroll listener was firing rAF + DOM mutations on every mobile scroll frame.

CSS — app/globals.css

• Moved scroll-behavior: smooth, overscroll-behavior-y: contain, and scroll-snap-type: none under @media (pointer: fine) so they never apply on touch devices

/* before: applied on all devices */
html {
  scroll-behavior: smooth;
  overscroll-behavior-y: contain;
}

/* after: desktop only */
@media (pointer: fine) {
  html {
    scroll-behavior: smooth;
    overscroll-behavior-y: contain;
    scroll-snap-type: none;
  }
}

JS — public/js/reactive-glow.js

• Added (pointer: coarse) guard around the scroll event listener; touch devices skip the rAF paint work entirely, matching the existing pattern in parallax.js

const isTouchDevice =
  typeof window.matchMedia === 'function' &&
  window.matchMedia('(pointer: coarse)').matches;

if (!isTouchDevice) {
  window.addEventListener('scroll', () => { /* rAF scale/opacity */ }, { passive: true });
}

Pull request overview

This PR reduces mobile scroll jank by preventing desktop-only scroll CSS and scroll-driven glow effects from running on touch devices, and bumps the release to v1.1.3 with dependency/CI action updates.

Changes:

• Scope scroll-behavior, overscroll-behavior-y, and scroll-snap-type to @media (pointer: fine) to avoid interfering with touch scrolling.
• Skip reactive-glow.js scroll listener work on (pointer: coarse) devices to reduce scroll-frame work on mobile.
• Bump version to 1.1.3, update react-icons, and refresh pinned GitHub Actions.
