No config needed. 32 hardcoded TLDs work offline as fallback.\n- **Dual-protocol engine** \u2014 RDAP-first with automatic WHOIS fallback. IANA server discovery covers ~189 ccTLDs that lack RDAP (`.es`, `.co`, `.eu`, `.jp`).\n- **Fast** \u2014 up to 100 concurrent checks, streaming results as they complete. 2.7 MB release binary.\n- **Domain generation** \u2014 pattern expansion (`\\w`=letter, `\\d`=digit, `?`=either), prefix/suffix permuta",
