/**
 * Playwright config for the env-routing test (B14).
 *
 * Scoped narrowly to `tests/env-routing.spec.ts` so it doesn't pull in
 * the integrations smoke harness (`tests/playwright.config.ts` →
 * `testDir: ./e2e`) or the shell-dashboard visual regression suite
 * (`shell-dashboard/playwright.config.ts` → `testDir: ./tests/visual`).
 *
 * Runs against LIVE deployments (staging + prod). No webServer block:
 * the test fetches public URLs; nothing local needs to be brought up.
 *
 * Usage:
 *   npx playwright test --config=showcase/playwright.env-routing.config.ts
 *
 * In CI this is gated to run after the B15 Railway env-var wiring
 * deploys settle.
