"""cryptpad — recipe-specific Playwright test (Phase 2 P3 + P6).

CryptPad is end-to-end client-side encrypted (plan §4.3: "client-side-encryption: page is
JS-rendered, so use Playwright, not bare curl"). This test exercises CryptPad in a real browser:

1. Browses to `/`.
2. Asserts the page title or content carries CryptPad branding (proves the SPA renders).
3. Asserts at least one of CryptPad's canonical asset paths (`/customize/`, `/components/`,
   `main.js`) is referenced in the rendered DOM (proves the SPA bundle is wired client-side).
4. Asserts no JavaScript console errors appeared during the SPA load (proves the JS pipeline
   initialized without breaking).

**Deferred (Q3.4 follow-up):** the full "create a pad → type content → reload → read-back"
test was attempted in earlier drafts but proved version-fragile across CryptPad releases — the
recipe under test (10.6.0+5.7.0) does NOT auto-redirect `/pad/` to a fragment-keyed pad URL, and
the precise UI selector for the "new pad" / "rich text" app launcher varies across CryptPad
versions. The maximal testable subset (SPA renders + JS bundle loads + no console errors) IS
implemented here; the create-and-read-back deeper test is tracked in BACKLOG-2 for a follow-up
that pins to a specific CryptPad app-launch contract (Adversary sign-off pending per plan §7.1).
