WordPress Blog Subfolder Migration

I’m moving my WordPress blog from **blog.joyandchaosshop.com** to **joyandchaosshop.com/blog** within our BigCommerce storefront. WordPress itself will stay on its current server; Cloudflare Workers will handle the reverse proxy that makes the blog appear under joyandchaosshop.com/blog...
