tcolorbox：tcbposter 更改注释样式

Question

有没有办法改变 showframe-annotations 的样式？
我想旋转col1, col2, ...90° 并设置字体\tiny。
这对于大量列（比如 30-50 列）很有用。

\documentclass{article}
\usepackage[margin=2cm, 
showframe=true]{geometry}
\usepackage[most]{tcolorbox}

\begin{document}
\noindent\begin{tcbposter}[
poster = {showframe=true, 
height=3cm, spacing=2mm, rows=2, columns=5,
height=6cm,  
},
boxes = {beamer, colframe=blue!50!black, colback=blue!50, colupper=yellow!50, 
},
]
\posterbox{name=A, row=2,  column=3,}{First box}
\end{tcbposter}
\end{document}

您可以尝试找到相应的片段代码并适应您的需求。

我在 里找到了tcb@poster@env。只需要改一行，但都是一起的。我不知道如何提取它。
