Nothing rolls freely
The seed chooses between authored options rather than sampling a range. The few values that are loose have ranges tight enough that both ends are good.
Seed
Every visit builds a structurally different version. The same seed rebuilds the same one, forever.
Variation is not
the same as chance.
Focal points are placed
Accent count is guaranteed and spread across depth, so no seed produces a version with nothing to look at.
Dependent values derive
Rolling stem weight and x-height independently closed the letter counters on roughly one seed in twenty. Deriving one from the other removed the whole class of failure.
Determinism is absolute
One stream consumed in a fixed order. Nothing calls the system random, so a link returns the exact version someone saw.
What the machine
does not decide.
The timing, the cut, the copy, and the order things happen in. Knowing what to withhold from a generator is the whole craft — a system that decides everything decides nothing well.
