/**
 * Base class for the Pages and Documents content-URL reports.
 *
 * Owns the shared metric set, configureView() defaults, configureWidgets(), and the per-report
 * scoped Requests documentation override. The error-status columns (page_not_found_404_requests,
 * server_error_5xx_requests) are registered in $this->metrics so they remain available via the
 * API, Custom Alerts, Scheduled Reports and Row Evolution — but the "show all columns" table
 * toggle is disabled because that view uses the Visitor Engagement preset which doesn't match
 * the BotTracking column schema (and would render an empty table).
 *
 * GetAIChatbotBrokenContent stays as a direct Report subclass — it has a different metric shape.
