+/**
+ * REFACTORED MARKDOWN PARSER
+ *
+ * This file has been refactored to improve readability and maintainability while preserving
+ * all existing functionality. Key improvements made:
+ *
+ * 1. Fixed regex escaping bug in parser function that prevented emphasis parsing
+ * 2. Renamed confusing function names (parse_ -> parseItalic, parse__ -> parseBold)
+ * 3. Improved list item detection to only match "* " (not just "*") to avoid conflicts with emphasis
+ * 4. Added comprehensive comments explaining each function's purpose
+ * 5. Used more descriptive variable names (list -> isInList, result -> htmlResult)
+ * 6. Simplified header parsing using regex instead of manual character counting
+ * 7. Improved code structure and flow for better readability
+ * 8. Added proper JSDoc documentation for the main parse function
+ *
+ * The parser now correctly handles:
+ * - Headers (# ## ### etc.)
+ * - Emphasis (*italic* and **bold**)
+ * - Paragraphs
+ * - Lists (* item)
+ * - Mixed content with proper list management
