+### Added
+- **Board Generate Now smoke (M4, skip-if-absent)** (`06-board-generate-now.spec.ts`).
+  Asserts the PRAutoBlogger board page loads, `#prab-generate-now` button is present
+  and carries a nonce, and the kick-off AJAX action returns valid JSON (no PHP fatal).
+  READ-ONLY: never waits for generation to complete; `kick_off()` is idempotent.
+  SKIPS with a loud annotation when `#prab-board` or `#prab-generate-now` is absent
+  (v0.21.0 M4 not yet deployed) so the e2e PR can merge before prautoblogger PR #166
+  per the M2/M3 merge-order binding. 27 tests total (was 25), delta = 2.

+/**
+ * 06-board-generate-now.spec.ts
+ *
+ * What: Smoke for the PRAutoBlogger board "Generate Now" control (v0.21.0, M4).
+ *       Asserts that the board page renders the generate-now button and that
+ *       clicking it sends the kick-off AJAX request without a PHP fatal.
+ *       Read-only assertions only — this test NEVER waits for article generation
+ *       to complete (that would make LLM API calls in CI).
+ *
+ * SKIP-IF-ABSENT (M4 binding): the generate-now surface ships with v0.21.0
+ *   (prautoblogger PR #166). This spec guards against the board container
+ *   (#prab-board) being absent or the generate-now button (#prab-generate-now)
+ *   missing. When those selectors are absent (v0.21.0 not yet deployed), the
+ *   entire test suite skips with a loud annotation so this PR can merge before
+ *   the plugin PR — matching the M2 merge-order binding.
+ *
+ * Selectors sourced from prautoblogger v0.21.0:
+ *   templates/admin/board-page.php: #prab-board, #prab-generate-now
+ *   assets/js/board-generate.js:    data-nonce, wp.ajax / admin-ajax.php
+ *
+ * Who triggers it: Playwright chromium project (post-auth setup).
+ * Dependencies: wp-admin authenticated session (from global.setup.ts).
+ *
+ * @see prautoblogger PR #166 (v0.21.0) — the surface under test.
