// ---------------------------------------------------------------------------
// Boots the cloud app's Vite dev server for the Playwright e2e suite — the SAME
// dev stack a developer runs (`bun run dev`), minus 1Password / real WorkOS.
//
// Everything here is a STUB: fake WorkOS creds, a fixed cookie/encryption key,
// and a throwaway PGlite on its own port (so it never collides with a running
// `bun dev`). That's deliberate — what the spec guards (the TanStack Start client
// entry hydrating) is a CLIENT-side module-graph concern that doesn't depend on
// any of these values, so the stub config is sufficient and the harness stays
// runnable in CI with no secrets.
//
// Used by `playwright.config.ts`'s `webServer`. Spawns the dev DB + Vite, wires
// their stdout through, and tears both down on exit.
