/**
 * phpcs:ignore WordPress.Files.FileName.InvalidClassFileName -- class naming convention differs from WordPress standard
 *
 * Registers and renders the Article Dossier admin page (M2).
 *
 * The dossier is link-accessed -- it is NOT a visible submenu item. It uses
 * the canonical hidden-admin-page pattern: register under parent 'options.php'
 * so WordPress computes the hookname as `admin_page_prautoblogger-dossier` at
 * BOTH registration time AND request time. The page is hidden from nav by
 * construction (options.php is a built-in WP page with no visible submenu block)
 * so no $submenu mutation is needed or permitted.
 *
 * Why NOT the hide-by-unset pattern (the v0.19.2 bug):
 *   add_submenu_page('prautoblogger-settings', ...) → hookname 'prautoblogger_page_prautoblogger-dossier'
 *   post-registration unset($submenu['prautoblogger-settings'][$idx])
 *   → at request time get_admin_page_parent() no longer finds the slug in $submenu
 *   → WP recomputes hookname in the 'admin_page_*' orphan namespace
 *   → no callback registered there → wp_die(403).
 * See ARCHITECTURE.md §22b + CONVENTIONS.md §Hidden Admin Pages for the full incident
 * history (board 404 v0.19.1, dossier 403 v0.19.2).
 *
 * Board cards and post-metabox deep-link here via
 * admin.php?page=prautoblogger-dossier&post_id=X. Deep-link URLs are parent-agnostic
 * (they reference only the page slug) so they are unchanged by this fix.
 *
 * Design contract: Proposal C "Editorial Record" -- warm editorial dossier,
 * verdict pills, receipt-style cost sidebar, per-stage I/O with raw-trace toggle.
 *
 * Triggered by: PRAutoBlogger::register_admin_hooks() on `admin_menu` (priority 12).
 * Dependencies: PRAutoBlogger_Dossier_Data_Assembler, templates/admin/dossier-page.php.
 *
 * @see admin/class-dossier-data-assembler.php -- Builds the view model.
 * @see templates/admin/dossier-page.php       -- HTML template.
