/**
 * Playwright configuration for SurfSense web E2E tests.
 *
 * Tests live under `tests/` and are NEVER bundled into the production Next.js
 * build (`.next/standalone/`) or the Electron desktop build, because:
 *   - This file and `tests/` are listed in `.dockerignore`.
 *   - `electron-builder.yml` only ships `.next/standalone/`, not source files.
 *   - `@playwright/test` is a `devDependency`, so production `pnpm install`
 *     with `--prod` skips it entirely.
 *
 * @see https://playwright.dev/docs/test-configuration
