出于美观原因，将侧边栏添加到单个框架（标题框架）

Question

这是我的第一篇帖子，如果我没有遵守所有规则，请原谅。

我正在尝试使用 beamer 为我的公司制作一个 LaTex 演示模板。除了标题页，我几乎已经拥有了我想要的一切。我需要一个仅在标题页中带有渐变的侧边栏，因为这是我们公司的标准标题页。我尝试在 \defbeamertemplate 中为标题页使用“\useoutertheme{sidebar}”，但它不起作用。还尝试使用 \useoutertheme 包装 \frame 定义，但也没有成功。由于对 beamer 还很陌生，我不知道还能做什么。

这是我的 MWE：

\documentclass{beamer}

\definecolor{dark}{rgb}{0.05, 0.3, 0.5}
\definecolor{light}{rgb}{0.1, 0.5, 0.7}

% Imports
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}

\usepackage[margin=1in]{geometry}
\usepackage{pythontex}
\usepackage[svgnames]{xcolor}

\renewcommand*{\thefootnote}{\fnsymbol{footnote}}

% Theme definitions
\DeclareOptionBeamer{compress}{\beamer@compresstrue}
\ProcessOptionsBeamer

\mode<presentation>

\useoutertheme[footline=title]{miniframes}
\useinnertheme{circles}

\setbeamertemplate{blocks}[rounded][shadow=true]

% Colors
\setbeamercolor{palette primary}{bg=dark, fg=black}
\setbeamercolor{palette secondary}{bg=light, fg=black}
\setbeamercolor{palette tertiary}{bg=dark, fg=white}
\setbeamercolor{palette quaternary}{bg=dark, fg=light}

\setbeamercolor{structure}{fg=black}

\setbeamercolor{titlelike}{parent=structure}
\setbeamercolor{title}{bg=light}

\setbeamercolor{item}{fg=light}
\setbeamercolor{itemize item}{fg=black}
\setbeamercolor{itemize subitem}{fg=black}

\setbeamercolor{institute in head/foot}{fg=white}

% Title page
\defbeamertemplate*{title page}{customized}[1][]
{
\begin{center}
    \usebeamercolor[fg]{titlegraphic}\inserttitlegraphic\par
    \usebeamercolor[bg]{palette primary}www.url.com\par
    \vspace{0.15\paperheight}
    \usebeamerfont{title}\inserttitle\par
    \vspace{0.6\paperheight}
    \usebeamerfont{subtitle}\usebeamercolor[fg]{subtitle}\insertsubtitle
\end{center}  
}

\mode
<all>

\title{Title}   
\titlegraphic{Title Graphic}
\logo{Logo}

\frame{
\frametitle{\insertsectionhead} 

}

\section{Second} 

\frame{

}

\end{document}

以下是我想要实现的目标：

• PS #1：我从其他模板复制了一些代码，所以可能有一些我不知道的无用的代码行
• PS #2：我不介意渐变与示例图像不完全相等（示例渐变从左侧的某种偏移/边距开始），但这对我来说是一个奖励

请注意，您不能使用\usepackage[margin=1in]{geometry}并且\usepackage[svgnames]{xcolor}——beamer 已经加载这些包，因此由于选项冲突，您的代码无法编译。
