+# Motion Advanced
+
+Complex, interactive, and physics-based animation patterns.
+Requires `motion-foundations` to be set up first.
+Use these when `motion-patterns` is not enough.
+
+## When to Activate
+
+- Building drag-to-dismiss sheets, swipe gestures, or reorderable lists
+- Animating text word-by-word, character-by-character, or as a live counter
+- Drawing SVG paths, morphing icons, or animating circular progress
+- Writing a custom animation hook (`useScrollReveal`, magnetic button, cursor follower)
+- Sequencing multi-step animations imperatively with `useAnimate`
+- Building spinners, shimmer skeletons, pulse indicators, or loading button states
+
+## Outputs
+
+This skill produces:
+
+- Drag interactions: draggable cards, drag-to-dismiss sheets, `Reorder.Group` lists
+- Gesture hooks: swipe detection, long press, pinch outline
+- Text animation components: word reveal, character typewriter, number counter
+- SVG animation: path draw-on, icon morph, stroke progress ring
+- Custom hooks: `useScrollReveal`, `useHoverScale`, `useNavigationDirection`, `useInViewOnce`
+- Imperative sequences via `useAnimate` with interrupt-safe `async/await`
+- Loader components: spinner, shimmer, pulse dot, progress bar, button loading state
+
+## Principles
+
+- Physics-based motion (`useSpring`, `springs.*`) always feels more natural than duration-based for direct manipulation.
+- `useMotionValue` + `useTransform` computes derived values without triggering re-renders.
+- `useAnimate` sequences are imperative and interrupt-safe — calling `animate()` mid-flight cancels the previous animation automatically.
+- Motion values (`useMotionValue`, `useSpring`) are SSR-safe and do not cause hydration errors.
+
+## Rules
+
+1. **Drag interactions must be tested on touch devices**, not just mouse. `drag` prop works on both but feel and threshold differ.
+2. **Infinite animations must pause when `document.visibilityState === "hidden"`.** Background tabs must not consume GPU/CPU.
+3. **Swipe threshold must be explicit.** Never infer intent from velocity alone; combine `offset` + `velocity` checks.
+4. **`useAnimate` scope ref must be attached to a mounted DOM element.** Calling `animate()` before mount throws silently.
+5. **Motion values must not be recreated on render.** `useMotionValue(0)` inside a component body is correct; `new MotionValue(0)` in a render is not.
+6. **All token values are imported from `motion-foundations`.** No inline numbers.
+7. **Custom hooks must handle cleanup.** Every `window.addEventListener` needs a matching `removeEventListener` in the `useEffect` return.
+8. **SVG morphing requires equal path command counts.** Paths with different command structures snap instead of interpolating.
+
+## Decision Guidance
+
+### Choosing the right advanced API
+
+| Scenario | API |
+| ------------------------------ | -------------------------------- |
+| Drag with physics on release | `drag` + `dragTransition: springs.release` |
+| Ordered drag-to-reorder list | `Reorder.Group` + `Reorder.Item` |
+| Dismiss on drag offset | `drag="y"` + `onDragEnd` offset check |
+| Swipe left/right | `drag="x"` + `onDragEnd` offset check |
+| Long press | `useLongPress` hook |
+| Value smoothed over time | `useSpring` |
+| Value derived from another | `useTransform` |
+| Multi-step sequence | `useAnimate` with `async/await` |
+| One-shot imperative animation | `animate()` from `motion` |
+| Text entering word by word | Stagger on `inline-block` spans |
+| SVG drawing on | `pathLength` 0 → 1 |
+| SVG morph | `d` attribute tween (equal commands) |
+| Circular progress | `strokeDashoffset` tween |
+
+### When to use `useSpring` vs a spring transition
+
+| | `useSpring` | `transition: springs.*` |
+| -------------- | ---------------------------------------- | ----------------------- |
+| Use for | Cursor follower, pointer-tracked values | Discrete state changes |
+| Updates | Continuous, on every frame | Triggered by state change |
+| Interrupt | Smooth — physics picks up from velocity | Restarts from current value |
+
+## Core Concepts
+
+### useMotionValue + useTransform
+
+Reactive computation without re-renders:
+
+```tsx
+const x = useMotionValue(0)
+const opacity = useTransform(x, [-200, 0, 200], [0, 1, 0])
+// opacity updates every frame as x changes — no setState, no re-render
+```
+
+### useAnimate
+
+Returns `[scope, animate]`. The scope ref must be attached to a DOM element.
+`animate()` calls are interrupt-safe — calling mid-flight cancels the previous run.
+
+```tsx
+const [scope, animate] = useAnimate()
+
+async function play() {
+  await animate(".step-1", { opacity: 1 }, { duration: 0.3 })
+  await animate(".step-2", { x: 0 },       { duration: 0.4 })
+        animate(".step-3", { scale: 1 },    { duration: 0.25 })  // fire and forget
+}
+
+return <div ref={scope}>...</div>
+```
+
+## Code Examples
+
+### Draggable card
+
+```tsx
+"use client"
+import { motion } from "motion/react"
+import { springs, motionTokens } from "@/lib/motion-tokens"
+
+<motion.div
+  drag
+  dragConstraints={{ left: -100, right: 100, top: -100, bottom: 100 }}
+  dragElastic={0.1}
+  whileDrag={{
+    scale: motionTokens.scale.pop,
+    boxShadow: "0 16px 40px rgba(0,0,0,0.2)",
+  }}
+  dragTransition={springs.release}
+/>
+```
+
+### Drag-to-dismiss sheet
+
+```tsx
+"use client"
+import { motion, useMotionValue, useTransform } from "motion/react"
+
+export function BottomSheet({ onClose }: { onClose: () => void }) {

+  const opacity = useTransform(y, [0, 200], [1, 0])
+
+  return (
+    <motion.div
+      drag="y"
+      dragConstraints={{ top: 0 }}
+      style={{ y, opacity }}
+      onDragEnd={(_, info) => {
+        // Rule 3: combine offset + velocity
+        if (info.offset.y > 120 || info.velocity.y > 500) onClose()
+      }}
+    />

+    <Reorder.Group axis="y" values={items} onReorder={setItems}>
+      {items.map((item) => (
+        <Reorder.Item key={item.id} value={item}>
+          {item.label}

+  dragConstraints={{ left: 0, right: 0 }}
+  onDragEnd={(_, info) => {
+    const swipedRight = info.offset.x > OFFSET_THRESHOLD  || info.velocity.x > VELOCITY_THRESHOLD
+    const swipedLeft  = info.offset.x < -OFFSET_THRESHOLD || info.velocity.x < -VELOCITY_THRESHOLD

+## End-to-End Example
+
+Drag-to-dismiss sheet with shimmer content, loading state, and reduced motion
+support — combining `useMotionValue`, `useTransform`, `useSafeMotion`,
+`AnimatePresence`, and tokens from `motion-foundations`:
+
+```tsx
+"use client"
+import { useState } from "react"
+import { motion, AnimatePresence, useMotionValue, useTransform } from "motion/react"
+import { springs, motionTokens } from "@/lib/motion-tokens"
+import { useSafeMotion } from "@/hooks/use-reduced-motion"
+import { ShimmerSkeleton } from "./shimmer-skeleton"
+
+export function DismissibleSheet({
+  isOpen,
+  onClose,
+  loading,
+  children,
+}: {
+  isOpen: boolean
+  onClose: () => void
+  loading: boolean
+  children: React.ReactNode
+}) {
+  const safe = useSafeMotion(motionTokens.distance.xl)
+  const y = useMotionValue(0)
+  const opacity = useTransform(y, [0, 200], [1, 0])
+
+  return (
+    <AnimatePresence>
+      {isOpen && (
+        <>
+          {/* Backdrop */}
+          <motion.div
+            key="backdrop"
+            className="fixed inset-0 bg-black/40"
+            initial={{ opacity: 0 }}
+            animate={{ opacity: 1 }}
+            exit={{ opacity: 0 }}
+            onClick={onClose}
+          />
+
+          {/* Sheet — drag-to-dismiss */}
+          <motion.div
+            key="sheet"
+            className="fixed bottom-0 inset-x-0 rounded-t-2xl bg-white p-6"
+            drag="y"
+            dragConstraints={{ top: 0 }}
+            style={{ y, opacity }}
+            onDragEnd={(_, info) => {
+              if (info.offset.y > 120 || info.velocity.y > 500) onClose()
+            }}
+            initial={safe.initial}
+            animate={safe.animate}
+            exit={safe.exit}
+            transition={springs.gentle}
+          >
+            {loading ? (
+              <div className="space-y-3">
+                <ShimmerSkeleton className="h-4 w-3/4" />
+                <ShimmerSkeleton className="h-4 w-1/2" />
+                <ShimmerSkeleton className="h-20 w-full" />
+              </div>
+            ) : children}
+          </motion.div>
+        </>
+      )}
+    </AnimatePresence>
+  )
+}
+```
+
+## Constraints / Non-Goals
+
+This skill does **not** cover:
+
+- Token and spring definitions → see `motion-foundations`
+- Standard UI patterns (button, modal, stagger, page transitions) → see `motion-patterns`
+- CSS-only animations or Tailwind `animate-*` without `motion/react`
+- Canvas or WebGL-based animation (Three.js, Pixi, etc.)
+- Full drag-and-drop systems with external state managers (dnd-kit, react-beautiful-dnd)
+- Game-loop or frame-by-frame animation
+
+## Anti-Patterns
+
+| Anti-pattern | Rule violated | Fix |
+| ---------------------------------------------- | ------- | ------------------------------------------------ |
+| `drag` tested only on desktop | Rule 1 | Test on touch emulator and real device |
+| `animate={{ repeat: Infinity }}` with no pause | Rule 2 | Add `visibilitychange` listener |
+| `onDragEnd` checking only offset, not velocity | Rule 3 | Check both `info.offset` and `info.velocity` |
+| `animate(scope, ...)` before `useEffect` | Rule 4 | Call `animate()` only after mount |
+| `const x = new MotionValue(0)` in render | Rule 5 | Use `const x = useMotionValue(0)` |
+| `transition={{ duration: 1.2 }}` inline | Rule 6 | Use `motionTokens.duration.crawl` |
+| `useEffect` without cleanup | Rule 7 | Return `removeEventListener` / `controls.stop` |
+| SVG morph between paths with different commands | Rule 8 | Normalize path commands before animating |
