How CalculatorShelf avoids low-value scale

• Every indexable calculator needs a working tool and crawlable default example.
• Pages need page-specific formulas, examples, mistakes, FAQs, and disclaimers.
• Safety-sensitive and underdeveloped pages can remain live but noindex until reviewed.
• No runtime AI is used to calculate results.
