+/**
+ * 07-peptide-news-admin.spec.ts
+ *
+ * What: Smoke tests for the Peptide News Plugin admin surfaces.
+ *       Verifies the dashboard, settings, articles, and cost sub-pages
+ *       load without PHP fatals and checks expected UI elements.
+ *       Guards against activation failures, missing menu registration, or
+ *       PHP fatals introduced by a bad deploy.
+ *
+ * Who triggers it: Playwright chromium project (post-auth setup).
+ * Dependencies: wp-admin authenticated session (from global.setup.ts).
+ *
+ * SKIP-IF-ABSENT: When the Peptide News Plugin is not installed/activated on
+ *   this environment, each test detects the absent menu page and skips with a
+ *   loud annotation — consistent with the 05/06 merge-early binding pattern.
+ *
+ * Admin menu slugs (sourced from admin/class-pn-admin-menu.php):
+ *   Dashboard  -> admin.php?page=peptide-news-dashboard
+ *   Settings   -> admin.php?page=peptide-news-settings
+ *   Articles   -> admin.php?page=peptide-news-articles
+ *   LLM Costs  -> admin.php?page=peptide-news-costs
+ *
+ * Selectors sourced from admin/partials/dashboard.php:
+ *   h1 "Peptide News Analytics"  - page heading (text match)
+ *   .pn-summary-cards            - summary card row
+ *   .pn-date-filter              - date range filter form
+ *
+ * @see peptiderepo/peptide-news-plugin admin/class-pn-admin-menu.php
+ * @see peptiderepo/peptide-news-plugin admin/partials/dashboard.php
