I believe that visual aids are more effective than text in illustrating the issue:
My Objective

Current Situation
Looking at the example, you can see that the title and description expand equally to accommodate the gallery. I aim to achieve a layout similar to the first image, where the gallery extends past the container and generates a scrollbar, allowing for minimal content in the left column.

* {
margin: 0;
}
.container {
background-color: aqua;
display: grid;
padding: 1rem;
grid-template-columns: 1fr min-content; /* Avoid setting a fixed width for min-content */
grid-template-rows: repeat(2, min-content);
grid-template-areas:
'title gallery'
'description gallery';
grid-gap: 1rem;
}
.gallery {
grid-area: gallery;
display: grid;
grid-template-columns: 8rem 8rem;
grid-auto-rows: 8rem;
grid-gap: 1rem;
overflow-y: auto; /* How do I have this overflow, depending on the cumulative min-content of the left column */
}
.gallery > * {
background-color: magenta;
}
h2 {
grid-area: title;
background-color: white;
}
p {
grid-area: description;
background-color: lightgrey;
}<div class="container">
<div class="gallery">
<div></div>
<div></div>
<div></div>
<div></div>
</div>
<h2>Some Title</h2>

</div>A Temporary Fix
To temporarily address the issue, I applied absolute positioning which necessitates knowing the width of the gallery in advance.
* {
margin: 0;
}
.container {
background-color: aqua;
display: grid;
padding: 1rem;
grid-template-columns: 1fr 18rem; /* Reserve space for the gallery */
grid-template-rows: repeat(2, min-content);
grid-template-areas:
'title gallery'
'description gallery';
grid-gap: 1rem;
position: relative /* Create a context for absolute positioning */
}
.gallery {
grid-area: gallery;
display: grid;
grid-template-columns: 8rem 8rem;
grid-auto-rows: 8rem;
grid-gap: 1rem;
overflow-y: auto;
position: absolute; /* Remove gallery from the flow */
top: 0; /* Align with the container's boundaries */
right: 0;
}
.gallery > * {
background-color: magenta;
}
h2 {
grid-area: title;
background-color: white;
}
p {
grid-area: description;
background-color: lightgrey;
}<div class="container">
<div class="gallery">
<div></div>
<div></div>
<div></div>
<div></div>
</div>

</div>Is there a way to achieve the desired layout without specifying a fixed width for the gallery? (And without using JavaScript). I haven't explored the use of flexbox yet, as my primary objective is to minimize the number of wrappers for optimal responsiveness. If achieving this with CSS grid alone is not feasible, I am open to reverting to flexbox.
