Valuation Lab: calculators and benchmark explorers

Ten interactive calculators and ten interactive benchmark pages, all running one tested calculation package with sourced, versioned data (benchmark snapshot 2026.09.22-1). Every calculator states its denominator, period and treatment of cash and debt; every benchmark keeps public trading, disclosed transactions and analyst ranges in separate, labelled views.
