Bump Contacts Permission Switch Interaction

This interaction reimagines the standard, dry system permission toggle into a delightful onboarding moment. When the user taps the custom switch, the knob slides to the right with smooth spring physics. Instantly, a burst of tiny, colorful confetti particles shoots out from the toggle, while the hand-drawn heart icon above it scales up with a bouncy overshoot. The 'merci' handwritten text and playful elements react dynamically, turning a routine setup step into a rewarding micro-interaction.
