How did u know it was Laravel
I've been with Laravel since the beginning and I know the standard templates of the emails. 😺 And the standard verification urls. The Twenty-One Portal was also built with Laravel.
And I can see Inertia.js :-) Also not used for a long time. We use Livewire, which is for the crazies who even start writing Javascript in PHP classes. If you want to hide JS code, a good option.
No inertia actually, routing is handled in react, Laravel just doing backend and returning json
