Summary by Sourcery

Improve overall documentation formatting for consistency and readability by standardizing footnote syntax, ordered list numbering, table styles, and paragraph wrapping across all Markdown files.

Documentation:

• Standardize footnote definitions and references using proper Markdown footnote syntax
• Ensure ordered lists consistently use numeric markers (e.g., “1.”) throughout the docs
• Convert HTML-based tables to native Markdown table syntax for better readability
• Reflow paragraphs and adjust line breaks to maintain a uniform line length and indent style in Markdown files
