/**
 * E2E config for the Design visual editor.
 *
 * Runs real Chromium against a dev server backed by a throwaway local SQLite
 * database (`data/e2e.db`). `global-setup.ts` signs up a test user, saves the
 * signed session as `storageState`, and seeds one design with a known fixture.
 *
 * Run: `pnpm e2e` (headless), `pnpm e2e:headed`, `pnpm e2e:ui`.
 * Override the target with `E2E_BASE_URL` (e.g. point at an already-running
 * server on :9300); then `webServer.reuseExistingServer` keeps it.
