playwright.config.js

/* Playwright configuration for DOMPurify browser tests.
 * Runs the QUnit suite in real browsers via Playwright's managed binaries.
 *
 * Browser coverage:
 *   npm test              -> chromium only (fast local dev / PR feedback)
 *   npm run test:browser  -> chromium + firefox + webkit (full engine coverage)
 *
 * The CI workflow's "browser-matrix" job runs test:browser on three OS runners
 * (ubuntu, macOS, Windows) giving 9 browser/OS combinations in parallel.
