Day 21 — hash-based routing for SvelteKit apps, for when you don't need (or can't run) a server. You can't use any server-side logic (including SSR), but other than, it's just like any other SvelteKit app

Another banger from Advent of @svelte.dev, whilst this was possible before having it built in to the framework and avoiding in-app bindings for these things is a big win.
This is just proving that small, incremental changes can make a huge difference to UX.

This design is straight out of Gotham and I'm all for that.
Until it breaks down. Maybe the pink one came to jump start the blue one.
