Input and output

• Options come from each calculator's input schema. Use the full name (--valuation-cap-usd), the short form without the unit (--valuation-cap), or any unambiguous words (--cap).
• Numbers accept $, commas and k / m / b suffixes: --invested 1.5m.
• Lists are comma-separated: --cash-flows 10000,25000,30000.
• Pass everything as JSON with --json '{"invested_usd": 100, "value_returned_usd": 300}' or pipe JSON on stdin. Flags override JSON.
• --output json prints { calculator, input, result } for scripts.
• Exit codes: 0 success, 1 unknown command, 2 invalid input.

Money is in US dollars (*_usd), percentages are percent numbers (20 = 20%, *_pct), multiples are plain numbers (2.5 = 2.5x) and dates are YYYY-MM-DD.
