nix-build (nixpkgs-23.11) then chroot. Then simple test

import { chromium, devices } from 'playwright';
import assert from 'node:assert';

(async () => {
    // Setup
    const browser = await chromium.launch({ headless: false });
    const context = await browser.newContext(devices['iPhone 11']);
    const page = await context.newPage();

    // The actual interesting bit
    await context.route('**.jpg', route => route.abort());
    console.log(1);
    await page.goto('https://example.com/');
    console.log(2);

    const pt = await page.title()
    console.log("page title");
    console.log(JSON.stringify(pt));

    assert(pt === 'Example Domain'); // 👎 not a Web First assertion

    const sleep = (ms: number) => new Promise((r) => setTimeout(r, ms))
    await sleep(5000)

    // Teardown
    await context.close();
    await browser.close();
})();

with chrome worked with the npx playwright install command meaning you can use the version the project was tested with.
