playwright.config.js

// Playwright config for the Decima 0.3 browser-rendered Shell qualification (WS1).
//
// The suite drives the REAL trusted Shell (served by tests/browser/serve_fixture.py over a
// real temporary Weft on a loopback port) through visible controls only. Each spec owns its
// own server + temp data dir via tests/browser/serverManager.js, so the durability specs can
// restart the backend and rebuild projections without disturbing other specs.
//
// Determinism on this ARM host: a single worker, no parallelism, no retries. Chromium is
// Playwright's OWN bundled build (npx playwright install chromium) launched with --no-sandbox
// (the host's /usr/bin/chromium raw launch hangs; the bundled headless-shell launches fine).
