Foundation Theme Shift On Scroll — Motion Lab

1. Mechanisme — kopieer 1-op-1, geen styling-keuzes

// Mechanisme: foundation-theme-shift-on-scroll
import gsap from 'https://esm.sh/gsap@3.12.5';
// Pas toe op je eigen selector — geen stijlkeuzes hier.
if(window.matchMedia('(prefers-reduced-motion: reduce)').matches)return;
const io=new IntersectionObserver(entries=>entries.forEach(e=>{if(e.isIntersecting)document.documentElement.setAttribute('data-theme',e.target.dataset.theme);}),{threshold:0.5});
document.querySelectorAll('[data-theme]').forEach(s=>io.observe(s));

2. Skeleton — DOM + class-namen, mag herschikken

<!-- Skeleton: foundation-theme-shift-on-scroll -->
<div class="demo-block">
  <!-- DOM-structuur hier -->
</div>

3. Styling-template — verplicht eigen invulling per merk

/* Styling: foundation-theme-shift-on-scroll */
:root {
  --block-bg: ;
  --block-fg: ;
  --block-accent: ;
}
