If your platform is adding trailing slashes to URLs, then you'll need to set trailingSlash: 'always' in your svelte.config.js

@Rich-Harris thanks, that solved it. I was baited by the demo into thinking it wasn't just me being an idiot. Since you're using Netlify to host the demo for testing, maybe it should have that setting on?

For a site built with adapter-static and hosted on GitHub Pages, setting trailingSlash: 'always' solves the problem. Thanks, Rich.
