Factorio Mod Validator

## known issues

Server and clients need matching mod zips.
Invalid info.json dependency syntax stops the server before gameplay.
Public visibility requires account verification and correct server settings.

## compatibility notes

Generated tweak mods are private zips until you publish them yourself.
Recipe unlock and prototype edits are deterministic data-stage changes.
Keep map preset notes with the save because server settings do not regenerate terrain.
