Honesty fine-print: this is a public page, checked on 2026-08-08 — anyone reading it can register these names, and availability changes daily. Treat the list as proof of method, not a private shortlist. Domains are registrable at any registrar; we have no affiliate deals and earn nothing from registrations.
