Feedback Indicators

This handles all the confirmation animations users expect after they do something: success checkmarks, error shakes, form validation feedback, save confirmations. It applies Disney animation principles to make feedback feel responsive and polished. You get timing recommendations for different scenarios (inline validation at 150ms, error toasts at 6 seconds), ready to use CSS for checkmark draws and error shakes, and auto-dismiss patterns. The timing tables are solid reference material. One thing to note: it leans heavily on animation, so you'll want to implement the prefers-reduced-motion fallbacks it mentions or risk annoying users who've disabled animations system-wide.
