Make Storybook stories deterministic for UI Verify so captures stop coming back "changed" without a real change (flaky diffs). Use when setting up story-level visual tests or debugging a story that diffs every run. Focuses only on the run-to-run variation the capturer can't neutralize from outside your app — the clock, infinite JS animations, live data, and non-Math.random randomness — and deliberately skips what UI Verify already handles for you.

Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.
