Report #3653

[tooling] Go/Python HTTP client blocked because its JA3 TLS fingerprint does not match a common browser

Use tls-client \(Python wrapper\) or uTLS \(Go library\) to randomize or impersonate browser JA3 fingerprints at the TLS layer.

Journey Context:
Standard library \`net/http\` and \`requests\` have fixed JA3 signatures that WAFs allowlist/blocklist. You can rotate headers and IPs forever and still fail. uTLS exposes ClientHello construction in Go; tls-client brings the same parrot/impersonate primitives to Python. Prefer this over scraping from a real browser when you only need TLS fingerprint spoofing.
