# Nulltongue Language Kit v0.3.0

Nulltongue is a terminal-safe visual writing system and constructed hacker language. Underlying text remains normal Unicode/UTF-8.

## v0.3 font family

This release introduces three practical terminal weights:

- Nulltongue Mono Regular (400) - slightly heavier than v0.2
- Nulltongue Mono Bold (700)
- Nulltongue Mono ExtraBold (800)
- matching Nulltongue Mono Nerd variants

Every style is provided as TTF, OTF, WOFF, and WOFF2. Nerd variants preserve Nulltongue printable ASCII while importing 10,000+ private-use/supplementary Nerd Font mappings.

All printable ASCII cells remain fixed-width (1233 font units in the current donor metrics). Higher Unicode remains inherited from DejaVu Sans Mono except deliberate Nerd Font ranges.

## Website builder specification

`PROJECT.md` defines Nulltongue Forge: a PHP 8.2+/HTML5/CSS3/vanilla-JS browser font editor using Canvas for spline/node editing, snapping, guides, measurement lines, font import, Nerd Font management, multi-weight editing, compilation, validation, versioning, and Language Kit release builds.

## Documentation

The v0.2 learner/reference books and reading tests remain the current language edition and are included unchanged in this v0.3 font/release update.

## Security

Nulltongue is visual obfuscation, not cryptographic protection. Changing the font or inspecting the underlying Unicode reveals the original text.
