ADR-004: Playwright over Cypress

Status: Accepted

Context

We need a reliable, cross-browser end-to-end testing and automated accessibility auditing framework.

Decision

We chose Playwright.

Rationale

Playwright offers multi-browser testing across Chromium, Firefox, and WebKit, isolated browser contexts, parallel execution, and built-in accessibility testing via @axe-core/playwright.

Consequences

E2E and accessibility test suites live in tests/e2e/. Playwright browsers are installed via mise run playwright:install.
