Folio

Restraint → creative flow.

A constraint-engine and authoring tool for picture books and early-reader literature. The engine measures developmental fit across phonology, vocabulary, syntax, and prosody. Authors bring the water; the tool reads the gauges.

Pre-alpha. The engine is being built first. This page exists so the deploy pipes are plumbed for the day there's something to paste in.
