// Usage: run `npm run test:browser` after `npm run build`; CI installs Chromium before execution.
// Limits: tests the generated artifact on loopback and does not replace live deployment identity verification.

//   module_name: playwright-config
//   module_kind: instrument
//   summary: Configures browser, route, static-math, and automated accessibility checks against the generated site.
//   owner: Erin Spencer
//   public_surface: npm run test:browser, npm run test:e2e, npm run test:a11y
