AEP2 Whitepaper - Additional Formatting Changes

Changes Made (2025-10-22 - Round 2)

1. Remove Page Headers ✅

• Before: Page header showing "AEP2 Whitepaper" on left and page number on right
• After: Clean pages with only page number at bottom center
• Removed header rule line

2. Remove Bold Text from Body Content ✅

• Removed all \textbf{} formatting from body paragraphs
• Kept bold only for:
  • Section, subsection, and subsubsection titles
  • List item labels (e.g., "Latency:", "Pre-funded balance", etc.)
  • Phase 1 and Phase 2 headings in section 4.1

Examples of removed bold:

• "human interaction" → human interaction
• "Agent Embedded Payment Protocol (AEP2)" → Agent Embedded Payment Protocol (AEP2)
• "authorize first, settle later" → authorize first, settle later
• "high-frequency micropayments" → high-frequency micropayments
• And many more throughout the document

3. Code Block for HTTP Header Example ✅

• Before: Plain text \texttt{} formatting
• After: Proper code block with frame

\begin{lstlisting}[language=bash, basicstyle=\ttfamily\footnotesize, frame=single, numbers=none]
X-Agent-Payment-Mandate: U29ycnlBYm91dE1h...bmRhdGVz
\end{lstlisting}

4. Fix Section Title Word Spacing ✅

• Problem: LaTeX justification was causing irregular word spacing in section titles
• Solution: Added \raggedright to all section title formats
• Result: Uniform word spacing in all section and subsection titles

\titleformat{\section}
  {\normalfont\Large\bfseries\raggedright}{\thesection}{0.5em}{}
\titleformat{\subsection}
  {\normalfont\large\bfseries\raggedright}{\thesubsection}{0.5em}{}
\titleformat{\subsubsection}
  {\normalfont\normalsize\bfseries\raggedright}{\thesubsubsection}{0.5em}{}
