You're on the root domain

Try foo.clawshots.dev or clawshots.dev — a single *.clawshots.dev wildcard domain alias routes any first-level subdomain to this one project, and this page just reads the Host header to tell them apart.

Two-level sub-subdomains like foo.bar.clawshots.dev are parsed correctly by this same code (see the "Depth" row above), but a flat *.clawshots.dev wildcard does not route them — Vercel/TLS wildcards only match one label. Serving those would need an explicit extra domain per parent, e.g. *.bar.clawshots.dev.
