 RDAP‑first domain registration lookups with WHOIS fallback. Produces a single, normalized record shape regardless of source.
 
-- RDAP discovery via IANA bootstrap (`https://data.iana.org/rdap/dns.json`)
-- WHOIS TCP 43 client with TLD discovery, registrar referral follow, and curated exceptions
-- Normalized output: registrar, contacts, nameservers, statuses, dates, DNSSEC, privacy flag, source metadata
-- TypeScript types included; ESM‑only; no external HTTP client (uses global `fetch`)
+- RDAP‑first lookup via [IANA bootstrap](https://data.iana.org/rdap/dns.json) with automatic WHOIS fallback when needed
+- Smart WHOIS client (TCP 43): authoritative TLD discovery, registrar referral follow, and curated exceptions
+- Rich, normalized results: registrar, contacts, nameservers, EPP statuses, key dates, DNSSEC, privacy flag, source metadata
+- RDAP enrichment: follows related/entity/registrar links (bounded) to fill in missing details
+- TypeScript‑first: shipped types, ESM‑only, zero external HTTP client (uses global `fetch`)
