## Contents

This crate contains the shared logic used by `farben` and `farben-macros`:

- **Lexer**: tokenizes farben markup strings into a `Vec<Token>`
- **Parser**: renders a token stream into an ANSI escape sequence string
- **ANSI**: color and emphasis encoding via SGR escape codes
- **Errors**: `LexError`, `RegistryError`, and `LexErrorDisplay`
- **Registry**: global named style store for `style!()` and `prefix!()`
- **Strip**: utilities for stripping ANSI, stripping markup tags, and escaping brackets
- **Degrader**: color degradation for terminals without truecolor support
- **Inline**: pre-processor for inline syntax (`*bold*`, `/italic/`, `` `code` ``)
- **Env**: runtime detection of `NO_COLOR`, `FORCE_COLOR`, and TTY status
- **State**: per-thread persistent style stack for bleed support
- **anstyle_conv**: bidirectional conversion with `anstyle` types (requires `anstyle` feature)
