SvelteKit is amazing. I disagree about Skeleton though. Skeleton makes you feel productive and safe at first but it has a lot of foot-guns. It leads you down a happy path until you don't like something and then it's difficult to customize. You're much better off using DaisyUI or something headless like MeltUI when it's ready.

Take a look at Skeleton's own site https://www.skeleton.dev/docs/get-started Press page down - no scrolling happens. Hover your mouse over the navbar - no scrolling. Print the page - the content is cropped to only what's shown on the screen. I've raised this with them and it hasn't been a huge priority yet tones of sites are using this pattern from the <AppShell> component. Skeleton thinks you can just take your dark theme, invert the colours and end up with a decent looking light theme which just isn't the case.

With DaisyUI you get a more mature/performant/popular framework that takes accessibility seriously. It's amazing what they can achieve with just CSS animations and no JS. It solves the hard part (HTML, CSS) and let's you write the easy part (Svelte). You're also less locked into Svelte - you can much easily pull your DaisyUI html into a different framework.
