-# DEPRECATED: Utilities for converting Lark grammars to Lezer format.

-# ⚠️ WARNING: This module is deprecated and will be removed in a future version.
-#
-# Original purpose:
-# - Transform a Lark grammar to a Lezer grammar for CodeMirror 6
-# - Extract completion items (keywords, operators, etc.) from a Lark grammar
-#
-# Deprecation reason:
-# - CodeMirror 6 requires a bundler (Webpack, Rollup, etc.)
-# - Incompatible with FastHTML's direct script inclusion approach
-# - Replaced by CodeMirror 5 Simple Mode (see lark_to_simple_mode.py)
-#
-# Migration path:
-# - Use lark_to_simple_mode.py for CodeMirror 5 syntax highlighting
-# - extract_completions_from_grammar() is still used and will be moved to utils.py
