/**
 * wp-embed-contract-test.php — prove deploy-method-4 (WordPress) EMITS THE RIGHT MARKUP,
 * with no WordPress installed.
 *
 * WHY THIS EXISTS — it graduates a status, not just a test. The WordPress plugin was
 * "BUILT, not shot": the PHP was complete but had never been RUN, so the 5x5 deploy matrix
 * could only ever claim 2 proven methods. wordpress/doxa-maps-embed/HOW-TO-TEST.md states
 * the correctness bar exactly: the wrapper must emit the same three things the catalog's
 * manifest.json ships as embed.script. That is checkable without wp-env or Docker -- stub the
 * ~20 WordPress functions the plugin actually calls (see wp-stubs.php), render the REAL
 * shortcode, and assert the output against the REAL built manifest.
 *
 * WHAT IT PROVES (and what it does not):
 *   PROVES  - the shortcode emits the element, a valid profile-config JSON payload, the bundle
 *             script at the correct catalog URL, the SRI integrity attribute via the
 *             script_loader_tag filter, and crossorigin=anonymous; and that a MALFORMED
 *             integrity is REJECTED (the negative test -- the format regex must actually fire).
 *   DOES NOT PROVE - that WordPress itself renders the page, that the block editor registers,
 *             or that a browser executes the result. Those still need a real WP install.
 *             Say "contract-proven, not WP-shot" and nothing stronger.
 *
 * Usage: php wordpress/tests/wp-embed-contract-test.php   (exit 0 pass / 1 fail / 2 no target)
 * Requires: php CLI + a BUILT tree (public/doxa-maps/manifest.json).
