Does this one count as a typo ?

Here it's written くらい (Kurai) but I'm sure it's ぐらい (Gurai).
Even in the artist page's description, it's written as "Gurai".

My dictionary says they're synonymous.

Really? Ok, thanks.
For me, it's been confusing until I checked the artist page to confirm that it was "Gurai".
Otherwise, I thought it was "Kurai" for "Somewhere dark" but then the meaning wouldn't go together with the picture and context.
