What makes Family, Family.
Summary
Family is a self-custody iOS wallet whose components people keep recreating, which is what prompted Benji to write down the sensibility behind them. This is not a tutorial and there is no animation code in it. The team settled on three principles: simplicity, fluidity and delight. Simplicity means the fundamentals are at hand and everything else appears when it becomes relevant, which matters most in flows like onboarding where the paths multiply. Fluidity keeps the experience continuous and delight builds a connection. Taken together they are a way of respecting the user's time and intelligence.

The design-engineering house style behind Sonner and Vaul.
Emil's main skill. Mostly animation, with the UI-polish and component judgement that surrounds it: what to build, how far to push it, and when to stop.

prototype
Builds several genuinely different UI variants behind a live picker.
Flip through real implementations instead of arguing about descriptions, then promote the one that wins.

Apple's interface and motion principles, translated for the web.
Distilled from the WWDC design talks. Gesture-driven UI, spring physics, interruptible transitions, translucent materials, optical sizing and the restraint underneath all of it.
