// Most tests are plain-TypeScript domain logic (no Svelte, no DOM) and run in
// the node environment. A few — notably the task-form registry's exhaustiveness
// test — import `.svelte` modules, so the Svelte and Paraglide plugins and the
// `$lib` alias are wired in to transform/resolve those imports. Components are
// only *imported* here (to assert coverage), never mounted, so no DOM/jsdom is
// needed. Vite resolves the `?raw` schema import natively.
