Since `serde-wasm-bindgen` doesn't support `#[serde(default)]` (https://github.com/cloudflare/serde-wasm-bindgen/issues/20),
we no longer able to deserialize a partial `Config` object. As a solution,
take care to pass a full object from the TypeScript side.
Configure [`importsNotUsedAsValues`](https://www.typescriptlang.org/tsconfig#importsNotUsedAsValues)
to `error`, and switch from `import` to `import type` where needed.
Also remove the `strict` configuration, as it's inherited from
`@tsconfig/recommended`.
This simplifies the `publicPath` function and makes it useable inside
`fetchRuffle`.
Assuming `publicPaths` isn't used anywhere, this shouldn't be harmless.
