📊 The Synchronicity Engine

Athena can tell you, in a reading, that she notices you keep drawing the same card — but that's an impression, not a measurement. This page is the measurement. It computes, across your entire reading history, how often each card has actually appeared compared to how often a genuinely random draw would produce it, and runs a real statistical significance test (a Poisson test, corrected for the fact that dozens of cards are being checked at once) before calling anything notable. If a card clears that bar, it means the deviation is unlikely to be chance alone — not proof of anything mystical, but a real, falsifiable pattern in your own data, which Athena can then interpret rather than guess at.
