Looks like you found a JS solution, here’s how you’d make the http redirect work for page → page redirects if anyone checks this out later
On the root page /
<meta http-equiv="refresh" content="0; url=https://therift.vip/">
<link rel="canonical" href="https://therift.vip/">
on foo.html
<meta http-equiv="refresh" content="0; url=https://therift.vip/foo.html">
<link rel="canonical" href="https://therift.vip/foo.html">
on bar.html
<meta http-equiv="refresh" content="0; url=https://therift.vip/bar.html">
<link rel="canonical" href="https://therift.vip/bar.html">
