我正在为研究论文准备一份 LaTeX 文档，但在格式上遇到了两个问题：
- 我希望左侧和顶部的边距为 4 厘米，右侧和底部的边距为 2 厘米。令我惊讶的是（对我来说）页边距在各个页面之间交替变化。
- 我尝试将页码放入页脚并希望它们居中。然而它们似乎稍微向两侧偏移了一点。
这是我的示例代码：
\documentclass[report]{apa7}
\usepackage{lipsum}
\setcounter{secnumdepth}{5}
\usepackage[american]{babel}
\usepackage{csquotes}
\usepackage[style=apa,sortcites=true,sorting=nyt,backend=biber]{biblatex}
\DeclareLanguageMapping{american}{american-apa}
\addbibresource{literatur/literatur.bib}
\renewcommand{\headrulewidth}{0pt}
\usepackage[T1]{fontenc}
\usepackage{ebgaramond-maths}
\usepackage{fancyhdr}
\fancyhf{}
\cfoot{\thepage}

\usepackage{geometry}
\geometry{

}
\let\llncssubparagraph\subparagraph
\let\subparagraph\paragraph
\usepackage[up,bf,raggedright]{titlesec}
