Technical Architecture & Execution Mechanics
Structural Markdown Synthesis
Font size hierarchies and typographic weight attributes (e.g. font-weight >= 700 or font-size >= 14pt) are normalized into corresponding markdown header levels (# through ###).
Header_Level = Math.min(3, Math.max(1, Math.round((Base_Size - Font_Size) / Scale_Factor)))Technical Limitations & Operational Constraints
- Heavily handwritten notes require manual OCR verification.
