README: the constant 1 in weight = 1 + log_b(amount/unit) is paid once per identity, so splitting
always pays until the log goes negative and no base fixes it; the defence lives outside the function.
Golden vectors (single and split k=1,2,10,100, three bases) computed with 60-digit decimal ln,
pinned by tests/golden.rs.

weight = 1 + log_b(amount/unit) in integer cents and micro-weights with an integer-only
log, plus floor, per-identity cap and minimum amount per identity; splitting_gain/curve
report what splitting a budget over k identities does. 11 property tests.
