/**
 * Coverage e2e suite — drives the **SvelteKit** SPA (built to `static-dist/`
 * with Istanbul instrumentation via `COVERAGE=1`) and collects per-test
 * `window.__coverage__` into `.nyc_output/` for an nyc report.
 *
 * The server is a debug `cargo run` on port 8088 serving the instrumented
 * SPA build. Production-shape end-to-end: OPAQUE + DPoP `required` are
 * both inherited from `tests/common/server.env` — the previous legacy
 * `./static` vanilla-frontend suite that overrode them off has been
 * retired.
 *
 * Build the instrumented SPA first:
 *   (cd frontend && COVERAGE=1 VITE_E2E=1 npm run build)
