Stellar Drift — Conlang Engine

Take roughly today's top languages, seed them across 150 worlds around 2700 AD, and isolate each world for a thousand years — the Beowulf-to-now gap. This engine models that drift for a single world. Every output is mutually unintelligible with its parent, and one parent seeded onto several worlds yields a family as diverse as Romance.

A seed plus a world card is the save file. Identical inputs always rebuild the identical language — sentences, glossary, and log byte for byte.
