Overlapping grid items using grid-template-areas / named areas - css

Question

I'm experimenting with CSS Grids, and this is the layout I'm building:
.grid {
display: grid;
align-items: center;
grid-template-columns: 1fr 4rem 1fr;
grid-template-rows: 1rem 1fr 1rem;
max-width: 900px;
margin: 0 auto;
}
.text {
/*
// Ideally, this should be
grid-area: text
*/
grid-column: 1 / 3;
grid-row: 2 / 3;
/* Fix z-index */
position: relative;
padding: 4rem;
background-color: #fff;
}
.image {
/*
// Ideally, this should be
grid-area: image;
*/
grid-column: 2 / 4;
grid-row: 1 / -1;
background-color: lightgray;
padding: 1rem;
/* Center das image */
display: flex;
justify-content: center;
}
/* Basic body */
body {
background-color: #fafafa;
font-family: sans-serif;
padding: 2rem;
}
img {
max-width: 100%;
height: auto;
}
<div class="grid">
<div class="text">One morning, when bobby woke from troubled dreams, he found himself transformed in his bed into a horrible vermin. He lay on his leg like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into
stiff sections.
</div>
<div class="image">
<img src="http://unsplash.it/400/400" />
</div>
</div>
(best to preview in full page...)
What I'd like to avoid:
.text and .image both currently are using grid-column: * / *; syntax, instead I'd like to use grid-area: text and grid-area: image;.
Is it possible to define grid-template-{columns|rows} as overlapping areas? I tried using second way of defining grid areas
, but that didn't seem to work.
Looks like you can't do [a-start] [b-start] [a-end] [b-end] in that syntax, or at least I didn't manage to.
So - Is there any way to create an overlapping grid using named areas?
I'm trying to use the named areas for convenience purely - so that it's easier to reason about the responsive layout code, instead of repeating myself multiple times in media queries.
Edit
Found the answer because of #vals answer below.
This seemed to work just fine, I probably made a syntax error in my previous attempt somewhere:
grid-template-columns: [text-start] 1fr [image-start] 4rem [text-end] 1fr [image-end];
grid-template-rows: [image-start] 1rem [text-start] 1fr [text-end] 1rem [image-end];

At least in a more basic layout, it seems to work for me:
.container {
border: solid 1px green;
height: 180px;
width: 300px;
display: grid;
grid-template-columns: [left-start] 100px [right-start] 100px [left-end] 100px [right-end];
grid-template-rows: [left-start] 60px [right-start] 60px [left-end] 60px [right-end];
}
.left {
grid-area: left;
background-color: red;
}
.right {
grid-area: right;
background-color: lightgray;
opacity: 0.5;
}
<div class="container">
<div class="left">
</div>
<div class="right">
</div>
</div>
