What to include

• The calculator URL.

How CalculatorShelf keeps pages useful

• Every finished calculator needs a working tool and a clear worked example.
• Pages need page-specific formulas, examples, mistakes, FAQs, and disclaimers.
• Some safety-sensitive or early-stage tools remain available as planning aids while examples and notes are expanded.
• No runtime AI is used to calculate results.
