For entertainment & reflection. Astrology, numerology and related interpretations are traditional systems, not scientifically validated predictions. Astronomical calculations are identified separately.

v0.17.1 adds Learn BirthLens, contextual explainers and TimeLab while keeping calculation and interpretation separate.

BirthLens methodology

🔭Astronomical fact

Physical position or time quantity.

🧮Deterministic calculation

Same rules + same inputs = same result.

🏛Traditional interpretation

Meaning assigned by a historical or modern tradition.

🧪Evidence assessment

Scientific or historical evaluation of claims.
