\section{Introduction}
\begin{frame}{What is the BJT Class?}
The \texttt{bjt} class is a personal Beamer class built on top of the
\textbf{Metropolis} theme.
It provides :
\begin{itemize}
\item A modern scientific presentation style
\item Modular theme architecture
\item Custom colors and typography
\item Physics-oriented shortcuts
\item Custom title and background pages
\item Backup slide management
\item Bibliography support
\item Easy customization
\end{itemize}
\end{frame}
%================================================

\section{Using the Class}
\begin{frame}[fragile]{Creating a Presentation}
Creating a presentation with the \texttt{bjt} class is straightforward.
\begin{adjustbox}{max totalsize={\textwidth}{0.7\textheight}}
\begin{lstlisting}
\documentclass{bjt}
% Presentation information
\newcommand{\Title}{Title} % (EDIT HERE)
\newcommand{\Subtitle}{Subtitle} % (EDIT HERE)
\newcommand{\AuthorName}{Name} % (EDIT HERE)
\newcommand{\InstituteName}{University} % (EDIT HERE)
\newcommand{\PresentationDate}{\today} % (EDIT HERE)
% Beamer metadata
\title{\Title} % (DO NOT EDIT HERE)
\subtitle{\Subtitle} % (DO NOT EDIT HERE)
\author{\AuthorName} % (DO NOT EDIT HERE)
\institute{\InstituteName} % (DO NOT EDIT HERE)
\date{\PresentationDate} % (DO NOT EDIT HERE)
\begin{document}
\titlepage
\end{document}
\end{lstlisting}
\end{adjustbox}
The \texttt{bjt} class automatically loads the theme and the required
packages, so no additional setup is necessary.
\end{frame}
%================================================
\section{Backgrounds}
\begin{frame}[fragile]{Title Background}
A custom title background can be added:
\vspace{0.5cm}
\begin{lstlisting}
\titlebackground[0.15]{image.jpg}
\maketitleframe
\end{lstlisting}
\vspace{0.5cm}
\begin{exampleblock}{}
\begin{itemize}
\item The first argument controls opacity.
\item Second one is the file name which you want to select as title-background.
\item The opacity argument is optional.
\item \textbackslash \textit{maketitleframe} command makes the titleframe.
\end{itemize}
\end{exampleblock}
\end{frame}
% set custom background to title
\titlebackground[0.12]{backgrounds/wallpaper.jpg}
\maketitleframe
\begin{frame}[fragile]{Slide Background}
Background images can also be applied globally:
\begin{lstlisting}
\slidebackground[0.15]{wallpaper.jpg}
\end{lstlisting}
The first argument controls opacity. The opacity argument is optional.
\vspace{1cm}
\begin{block}{Note}
Using \textbackslash \textit{slidebackground\{\}} resets the previously applied background.
\end{block}
\end{frame}

%================================================
\section{Typography}
\begin{frame}{Design Philosophy}
The class follows a modular structure.
\begin{block}{Core Theme}
Controls global appearance:
\begin{itemize}
\item Colors
\item Fonts
\item Inner theme
\item Outer theme
\end{itemize}
\end{block}
\vspace{-0.2cm}
\begin{exampleblock}{Templates}
Provides reusable components:
\begin{itemize}
\item Title page
\item Backgrounds
\item References
\item Backup slides
\end{itemize}
\end{exampleblock}
\end{frame}
\begin{frame}{Fonts}
This theme uses
\begin{itemize}
\item Bookman as the text font
\item EulerVM for mathematics
\item Small-cap frame titles
\item Serif font theme
\end{itemize}
Example:
\begin{align*}
E &= mc^2\\[1ex]
\int_0^\infty e^{-x^2}\,dx &= \frac{\sqrt{\pi}}{2}
\end{align*}
\end{frame}
%================================================
\section{Blocks}
\begin{frame}{Block Environments}
\begin{block}{Normal Block}
This is the standard block.
\end{block}
\vspace{3mm}
\begin{alertblock}{Alert Block}
Use this for warnings or important remarks.
\end{alertblock}
\vspace{3mm}
\begin{exampleblock}{Example Block}
Useful for examples and exercises.
\end{exampleblock}
\end{frame}
%================================================
\section{Lists}
\begin{frame}{Itemized Lists}
The itemize environment uses customized checkmarks.
\begin{itemize}
\item First item
\item Second item
\item Third item
\end{itemize}
\vspace{5mm}
Enumerations are changed as follows.
\begin{enumerate}
\item One
\item Two
\item Three
