Names must match `[a-z][a-z0-9_]*` and override the built-in four (alpha, safe, num, special). Avoid duplicate characters; himi warns if it sees them, since they skew the distribution and overstate entropy.
Names must match `[a-z][a-z0-9_]*` and override any built-in of the same name (alpha, safe, num, special, hex, b58, b64, alnum, ascii). Avoid duplicate characters; himi warns if it sees them, since they skew the distribution and overstate entropy.
Range tokens pick the length weighted by `size^L`, so every possible output is equally likely. `{num:1-2}` covers 0-99 plus 0-9 (110 outcomes, ~6.8 bits), not a 50/50 coin flip on length, which would tank min-entropy.
