✓100% Local & Offline: cat detection, segmentation, and card generation all run on-device.
✓Real Neighborhood Discovery: every card starts from an actual photo of an actual stray cat.
✓Physics-Feel Throwing: a hand-tuned drag/flick/arc system, not a simple tap-to-catch.
✓Rarity-Scaled Challenge: Legendary encounters roll a genuinely smaller, faster catch window.
✓Living Card Collection: every card tilts and shimmers via gyroscope/touch, with a rarity-scaled holographic effect.
