定理标题位于外边距（偶数/奇数页）

Question

我希望定理/定义/等标签出现在外页边距（考虑偶数页和奇数页）。首先，我尝试使用包thmtools（下面的代码和图片）。但是，我只能将标签始终放在左边距。特别是，我不知道如何thmtools与结合ifoddpage。

接下来，我尝试了ntheorem（下面的代码和图片）。使用ntheorem，标签放置工作正常，但我无法更改定理标题的字体样式（下图中的“一些重要定理”）并将其放在一行上。此外，我无法摆脱缩进。最后，它还破坏了我的autoref参考资料。

到总结：我正在寻找一个允许的定理环境

• 标签外页边距（奇数页/偶数页）
• 标签、标题和正文的完全样式控制
• autoref兼容性（特别是，我想对不同的定理环境（例如定理，定义等）使用单个计数器）

我快要放弃了，所以我真的希望有人能帮助我。

代碼thmtools：

\documentclass[10pt, a4paper, twoside]{article}
\usepackage[a4paper, inner=1.25in, outer=1.25in]{geometry}

\usepackage{color}
\usepackage{amsthm}
\usepackage{thmtools}

\newlength{\spaceblength}
\settowidth{\spaceblength}{\bfseries\ }
\declaretheoremstyle[
    headfont=\bfseries,
    notefont=\bfseries,
    notebraces={}{\\[\parskip]}, % Braces for additional text
    bodyfont=\normalfont\itshape,
    headpunct={},
    headformat={%
        \makebox[0pt][r]{\color{red}\NAME\ \NUMBER\ \ }\hskip-\spaceblength{\NOTE}%
    }
]{boxstyle}

\declaretheorem[style=boxstyle,numberwithin=section]{theorem}
