/*
 * git-sync BROWSER e2e — drives the real Docmost web UI with Playwright to
 * reproduce the exact user flow that previously caused data loss: pages created
 * in the browser start UNTITLED (all collapse to the `_` vault filename); typing
 * a title reshuffles that collision and used to TRASH another live page. This
 * test creates several pages via the UI, titles one, runs a sync, and asserts
 * NOTHING was moved to Trash.
 *
 * Setup: needs Playwright + a Chromium build. The project should add
 * `@playwright/test` as a devDep (`pnpm dlx playwright install chromium`). This
 * script resolves playwright-core + the chromium binary from env so it can run
 * against an already-installed browser:
 *   PW_CORE=/path/to/node_modules/playwright-core
 *   PW_CHROME=/path/to/chrome
 * and the live stand env (SERVER/SPACE_ID/EMAIL/PASSWORD/DB_CONTAINER) like the
 * shell e2e suites.
