I wouldn't judge any JS framework like SvelteKit or Next.js on its lacking in the backend. They have a server to handle frontend problems, not solve your backend problems.
My setup requires multiple monitors. Having at least 2 monitors then a laptop on the side. Turn all notification sound off and make sure the slack red dot stays on laptop screen, on the edge of your peripherals.
While focusing on work it will be harder to notice the red dot but won't be turned off.
Music helps when it's hard to focus, I prefer some genre of instrumentals.
I see folks get "participation trophies" all the time, they come in different forms.
