/**
 * 05-dossier-edit.spec.ts
 *
 * What: Smoke for the PRAutoBlogger dossier EDIT + RE-RUN surface
 *       (plugin v0.20.0, Phase 2 admin M3). Read-only: opens/closes the
 *       edit panel and asserts structure — it NEVER clicks Save or any
 *       Re-run button (those fork inputs / queue paid LLM jobs).
 * Who triggers it: Playwright chromium project (post-auth setup).
 * Dependencies: wp-admin authenticated session (from global.setup.ts).
 *
 * SKIP-IF-ABSENT (M3 binding): this spec targets a surface that may not
 * be deployed yet. When the M3 markup (.prab-stage-rerun-footer) is
 * absent from the dossier, the test SKIPS with a loud annotation so this
 * PR can merge before the plugin PR ships. Once v0.20.0 is live, the
 * skip path goes dead and the assertions gate as usual.
 *
 * Selectors sourced from prautoblogger v0.20.0:
 *   templates/admin/dossier-stage-section.php  (.prab-stage-rerun-footer,
 *     .prab-edit-toggle, .prab-edit-unavailable, .prab-rerun-from)
 *   templates/admin/dossier-edit-panel.php     (.prab-edit-panel,
 *     .prab-edit-textarea, .prab-edit-save, .prab-edit-rerun)
 *   templates/admin/dossier-sidebar-cards.php  (.prab-run-spend,
 *     .prab-models-card)
 *
 * @see prautoblogger PR #161 (v0.20.0) — the surface under test.
