Custom Frame Environment

Use the shibuiframe environment for highlighted content boxes:

\begin{shibuiframe}{Title}
  Your content here
\end{shibuiframe}

Code and Algorithms

The theme automatically styles code listings and algorithms with proper background colors:

\begin{frame}[fragile]{Code Example}
  \begin{lstlisting}[language=Python]
  def hello():
      print("Hello, World!")
  \end{lstlisting}
\end{frame}

\begin{frame}{Algorithm Example}
  \begin{algorithm}[H]
    \caption{Your Algorithm}
    \begin{algorithmic}[1]
      \State Your pseudocode here
    \end{algorithmic}
  \end{algorithm}
\end{frame}

Frame Breaks

The theme properly handles multi-page frames with continuation numbers:

\begin{frame}[allowframebreaks]{Long Content}
  % Content that spans multiple slides
  % Will show "Long Content", "Long Content I", "Long Content II", etc.
\end{frame}

Navigation

The navigation bar (when navontop is enabled) shows:

• Section names: Clickable links to jump to each section
• Circles (optional with navcircles): Show slides within current section
• Current section is highlighted in accent color

Design Philosophy

Shibui embodies Japanese minimalist design principles:

• Clarity through simplicity - No unnecessary decorations
• Generous whitespace - Content room to breathe
• Elegant typography - Readable, beautiful fonts
• Subtle navigation - Present but unobtrusive
• Focus on content - Design serves the message

The aesthetic aims for restrained elegance, where beauty emerges from simplicity and attention to detail rather than ornamentation.
