Startup financial-health score (A-F) API

Transparent weighted startup financial-health rubric (0-100, graded A-F) over five 0-1 factors with explicit weights — runway 0.25, growthEfficiency 0.20, retention 0.20, grossMargin 0.20, unitEconomics 0.15 — with a per-factor contribution breakdown. Answers 'how healthy is my startup','what grade is my startup's financials','which financial factor drags me down'.
