v2.0.0: focus on 3 tools
liftmath is now a simple gym calculator — one-rep max, plate loading, and strength scores.
Trimmed from ~26 calculators down to 3 that you actually reach for:
- 1RM: 6 formulas + median consensus
- Plates: greedy loading + finite-inventory solver
- Strength score: Wilks (2020 + original), DOTS, IPF GL
Python package: 75 tests ✓, zero deps, Python 3.10+
Web app: mobile-first PWA, fully offline, installable, dark by default
