Scales the whole page up by 15% on every visit, using zoom or a transform fallback.

Code to copy

(function () {
    var ZOOM = 1.15;
    var b = document.body;
    if (!b) return;
    b.style.setProperty('zoom', String(ZOOM));
    if (!('zoom' in b.style) || getComputedStyle(b).zoom === '') {
        b.style.setProperty('transform', 'scale(' + ZOOM + ')', 'important');
        b.style.setProperty('transform-origin', 'top center', 'important');
        b.style.setProperty('width', (100 / ZOOM) + '%', 'important');
    }
})();
