Module code_languages 

Language normalization and metadata for code blocks. Code fence language normalization.

This module exists so both the editor and viewer can share:

• a small, curated list of common language aliases
• consistent display labels (e.g. rs -> Rust)

The core renderer also uses this to populate data-language on <pre> so CSS themes can show a proper label instead of a generic “Code”.

Constants

KNOWN_CODE_LANGUAGES

A small, human-curated set of common languages and their aliases.

Functions

language_display_label

Returns a display label for a fenced code language.
