Release notes
⚠️ Breaking changes:
- API is now simpler:unitBezier(p1x, p1y, p2x, p2y) returns (x, epsilon?) => y. Replaces the new UnitBezier(...).solve(...) class API.
- Removed sampleCurveX, sampleCurveY, sampleCurveDerivativeX, solveCurveX, and the stored p1x/p1y/p2x/p2y fields — none were used by primary consumers like GL JS.
- Switched to native ESM ("type": "module").
