Subject: [PATCH 2/2] Fix incorrect Markdown italic parsing for '_' breaking
 LaTeX math expressions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Disable underscore-based italic substitution to prevent corruption of LaTeX indices (e.g., x_i → x\textit{i}). This ensures that mathematical expressions like x_{i} and a_{ij} are preserved correctly during LaTeX export.
