Derive the 49-byte header seed and the salt F per-session from the grok homepage (browser-free tls-client GET), instead of hardcoding constants that go stale on every grok web rebuild (403 anti-bot). F is reproduced natively in Go (curve keyframe sampling: cubic-bezier easing, color lerp, rotation matrix, JS-exact number->hex). Static constants remain as env-overridable fallback. Adds offline regression test against server-verified ground-truth triples.
