A production-grade Magento 2 profiler that traces every block render, observer, plugin, layout phase, DI resolution, and SQL query in a request, detecting bottlenecks (slow/N+1 queries, slow blocks/observers, heavy modules) with severity, estimated savings, and the exact file:line. Includes a storefront toolbar, admin grid, userland-vs-core split, and XLSX/PDF reports.
