Utilizo el paquete tcolorbox para producir cuadros titulados. Puse el nodo del título en la esquina derecha del cuadro pero se superpone al texto del ejemplo. ¿Cómo puedo hacer un cuadro con el nodo de título en la esquina derecha y el texto "envuelto" alrededor de él, de modo que el texto del ejemplo se detenga cuando llegue al nodo y continúe en la nueva línea? Doy un ejemplo mínimo.

\usepackage[most]{tcolorbox}
\usepackage{array}
\tikzstyle{titlenode} =

line width=0.1pt, text=black, rectangle,

Thanks to @David Carlisle, I obtain boxed examples, with text wrapped around the title node,
with the command "0pt \dimexpr \hsize-3cm\relax", which is not very far from my aim. Clearly,
I doesn'nt want to write the commands...
"\parshape 4
0pt \dimexpr \hsize-3cm\relax
0pt \dimexpr \hsize-3cm\relax
0pt \dimexpr \hsize-3cm\relax
0pt \hsize"
at every beginning of example.
How can I write a macro which inserts automatically the command \parshape 4,
and 3 lines with the command "0pt \dimexpr \hsize-3cm\relax" at the beginning of each
example ?...
I give the tex file I use

Si ejecuto su ejemplo no obtengo la línea superior, pero esto agrega el recorte:
