Rotating, unlinkable anonymous device tokens for privacy-preserving proximity counting. A token is derived from a random per-install seed hashed with a time window: strangers can count nearby devices right now, but can't recognize the same device across windows, days, or link it to an identity. Pure Dart, no plugins. Extracted from the ParkerUp parking app's BLE presence beacon.
