Everyone please calm down with the gigantic fisher-price rounded corners on everything (especially you, Google)

reasonable-corners.js

_chill_factor = 0.25;
_chill_threshold = 5; // px

for (const el of document.querySelectorAll('*')) {
  for (const _corner of ['TopLeft', 'TopRight', 'BottomRight', 'BottomLeft']) {
    _prop = 'border' + _corner + 'Radius';
    if (window.getComputedStyle(el)[_prop] !== '0px') {
      _rad = parseInt(window.getComputedStyle(el)[_prop]);
      if (isNaN(_rad) || _rad <= _chill_threshold) {
        continue;
      }
      _vrad = Math.min(_chill_threshold, Math.floor(_rad * _chill_factor));
      // console.log(_prop, _rad + 'px', _vrad + 'px', el);
      el.style[_prop] = _vrad + 'px';
    }
  }
