// builds, but Vitest's browser build does not — so esbuild's optimizeDeps scan
// follows the import into sharp and dies bundling its native
// `require('../build/Release/sharp-*.node')`, killing the WHOLE component suite
// before any test runs. (The tests `vi.mock` server-side-helpers, but that is a

//                  only, so `.tsx` is already excluded — the glob is explicit
//                  belt-and-suspenders). See `test/component-setup.tsx`.
