 "method": "HMAC-SHA256(key = seed bytes, message = 8-byte big-endian counter from 0); each block gives eight 32-bit big-endian words; an integer in [lo, hi] is lo + w mod n for the first word w below the largest multiple of n under 2^32 (words above it are skipped); picks without repeats are a partial Fisher-Yates shuffle from the front."
