-         *  - it goes through the GENERIC `mintProofs('onchain', ...)` rather than

-         *    how we learn which derivation indices the library actually consumed.
-         *    Losing that would desync our counter and risk blinded-secret reuse.
-         *    The generic form takes the full MintProofsConfig, which carries BOTH

-         *    reads that off the quote object.
