how to round corners of shaded boxes

Question

I have a shaded text box looking as:

which is generated by the following code?

\documentclass{memoir}
\usepackage{titling}
\usepackage{algorithm,algpseudocode}
\usepackage{bm}  % bold greek variables (boldmath)
\usepackage{tikz}
\usetikzlibrary{positioning}  % use: above left of, etc
\usetikzlibrary{calc}
% Required for the ToDo list.
\usepackage{ifthen}
\usepackage[protrusion=true,expansion=true, kerning]{microtype}
\usepackage{enumitem}
\usepackage{booktabs}
\usepackage{lipsum}
\usepackage{wrapfig}
\newcommand{\secref}[1]{Section~\ref{#1}}
\newcommand{\chapref}[1]{Chapter~\ref{#1}}
\renewcommand{\eqref}[1]{Equation~(\ref{#1})}
\newcommand{\figref}[1]{Figure~\ref{#1}}
\newcommand{\tabref}[1]{Table~\ref{#1}}
\begin{document}
\definecolor{shadecolor}{RGB}{176,224,230}%{246,243,226}
\setlength\OuterFrameSep{0pt}
\begin{shaded}
    % \medskip 
    \textcolor{gray}{}\
    \textcolor{gray}{\textbf{Chapter 1}}\
    \textcolor{dark_red}{\textbf{SUMMARY: }}
    \medskip \

    Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text, 
\end{shaded}
\setlength\OuterFrameSep{0pt}
\begin{shaded}
    % \medskip 
    \textcolor{gray}{}\
    \textcolor{gray}{\textbf{Chapter 2}}\
    \textcolor{dark_red}{\textbf{SUMMARY: }}
    \medskip \

    Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text,Some text, 
\end{shaded}
\end{document}

Is there a way to round the corners while keeping rest of the visual features intact?

Please extend your code snippets to complete but small document beginning with \documentclass and ending with \end{document} which we can test as they are. Do you look to tcolorbox package? — Zarko, Nov 30 '20 at 09:00
The updated code given does not compile. Please correct it so that it reproduces the problem. — Peter Grill, Nov 30 '20 at 09:52

Perhaps tcolorbox makes things easier.

You did not include the environment shaded (perhaps from framed ?) in your code, so I commented these lines.
