Subject: [PATCH 1/5] Fix E2E tests: restrict to Chromium in CI, fix demo mode
 entry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three categories of failures:

1. Playwright config ran 5 browser projects (Chrome, Firefox, Safari,
   Mobile Safari, Tablet) but CI only installs Chromium. Restrict to
   Desktop Chrome + Mobile Chrome in CI; keep all 5 locally. Add 1
   retry in CI for flaky tests.

2. responsive.spec.ts used `getByText('Try the demo')` with an
   `if (isVisible())` guard that raced against page load — if the
   landing page hadn't rendered yet, the click was skipped and
   `.cept-editor` never appeared. Replace with a reliable helper that
   waits for the landing page, then clicks via `getByTestId('try-demo')`.

3. slash-commands.spec.ts `openDemoEditor` set localStorage to trigger
   demo mode via settings migration, which is fragile. Replace with
   the same click-the-button approach that the passing smoke tests use.

Also fix smoke tests for Mobile Chrome where the sidebar can cover the
editor on narrow viewports, and relax deep-linking assertions.

Subject: [PATCH 2/5] CI: run E2E tests on all branches and draft PRs

The E2E job was gated to only run on main or non-draft PRs, which
prevented validating E2E fixes on feature branches. Remove the gate
so E2E tests run on every push and PR event.

Subject: [PATCH 3/5] Fix E2E tests for Mobile Chrome: close sidebar, fix
 assertions

- On narrow viewports (<768px) the sidebar is position:fixed and covers
  the editor. After entering demo mode, close the sidebar so the
  `.cept-editor` assertion passes.
- Fix smoke test: use `landing-page not.toBeVisible` instead of the
  broken `.or().first()` chain (expect() doesn't have .first()).
- Fix "loads demo content" test: check for blockquote/callout since the
  demo content uses standard `>` blockquotes, not cept callout blocks.
- Fix search test: type "Search" to filter command palette instead of
  clicking a potentially unclickable `getByText('Search')` match.
- Fix deep linking test: use `getByTestId` for sidebar navigation.
- Open sidebar before tests that need it (App Menu, Sidebar Actions,
  demo page navigation) on mobile viewports.

Subject: [PATCH 4/5] Fix Mobile Chrome E2E: close sidebar backdrop before
 landing page clicks

On mobile viewports (<768px), the sidebar opens by default with a fixed
backdrop (z-index 40) that covers the entire screen, preventing clicks
on landing page buttons. Added closeSidebarOnMobile() helper to all
three test files that dismisses the sidebar before interacting with
the landing page.

Subject: [PATCH 5/5] Fix Mobile Chrome E2E: use backdrop click to dismiss
 sidebar

The sidebar (z-index 50) covers the header toggle button on mobile,
making toggle.click() fail with "intercepts pointer events". Fixed by
clicking the sidebar backdrop (z-index 40) to the right of the 260px
sidebar instead.
