Reading this through Materialistic, I get a flash of the site seemingly perfectly rendered, then the whole site disappears and is replaced by an error message. What kind of insane JS framework is doing this, why does it exist and why is it used on this landing page? If I keep spamming the refresh button, I can read the site just fine, so whatever this error is, it sure as hell isn't critical: TypeError: Cannot read properties of null (reading 'setItem') at https://jsonhero.io/build/_shared/chunk-BBURKVQ4.js:17:160084
