client diversity
20 distinct client stacks reach this name.
concentration
0.573 traffic splits near-evenly across many unrelated stacks.

Spread is entropy over the fingerprints reaching this domain, not over the domains a fingerprint reaches. It can’t distinguish one scraper from many people — it measures the mix of software, not who runs it.

Apple Safari / WebKit
Apple SecureTransport cipher-suite signature — Safari (macOS/iOS), WKWebView, and native URLSession apps; the 3DES legacy tail (0xC008/0xC012/0x000A) is Apple's tell, no other modern stack carries it. Platform entry like Android's Conscrypt: Apple system TLS legitimately offers any ALPN (h2, http/1.1, dot, none), so the cipher list alone is the signature — not ALPN-gated
