When to Use Commas With Adverbial Clauses
https://www.pristineword.com/comma-adverbial-clause/#google_vignette
It is possible to drop the comma if the clause is clear, quite short, and
does not require a pause.
Wherever she goes trouble seems to follow.
3. Exceptions
There are exceptions to this convention of not using commas when the
adverbial clause follows the main clause.
3.1 'Although', 'Even though', and 'Whereas'
When there is a strong contrast between two clauses, place a comma for
clauses introduced by whereas, although, though, or even though.
Peter was sad, although he had won a Nobel Prize.
3.2 Setting off Nonessential Clauses
Use commas to set off nonessential clauses, that is, clauses that can be used
as an aside.
I rarely eat fried food, although I like it, because it's unhealthy.
3.3 Comma Before Because
Place a comma before "because" only if needed for clarity.
I didn't do the job, because I was busy. (I didn't do the job due to the fact
that I was busy.)
