/**
 * 02-peptide-search.spec.ts
 *
 * What: Smoke-tests the Peptide Search AI (PSA) frontend search widget.
 *       Verifies the [peptide_search] shortcode renders, accepts input,
 *       and returns results for a known-good peptide name. Catches AJAX
 *       failures, nonce issues, and missing PR Core dependency.
 * Who triggers it: Playwright chromium project (post-auth setup).
 * Dependencies: peptide-search-ai plugin + PR Core active; at least one
 *               published peptide CPT post (e.g., BPC-157) on staging.
 *
 * @see C:\Users\ongte\apps\Peptide Repo CTO\app-maps\peptide-search-ai.md
