TAG ‖ xonly(32) ‖ salt(32) — the salted message that gets BIP-340 signed.
The salt replaces v1's pinned index as the source of per-artifact
uniqueness, which is what lets a key that repeats across artifacts still
derive a distinct preimage for each. It is public: knowing it yields nothing
without the seed.
