+# Accordion CSS Animation & Keyframe Library
+
+## Description
+This PR adds a comprehensive CSS Animation and Keyframe library to the `accordion` component. It provides five production-ready keyframe animations (fade-in-up, scale-in, pulse, spin, shimmer) with stagger delay utilities, all using only `transform` and `opacity` to remain on the GPU compositor thread.
+
+All animations are fully accessible and automatically disable when users have `prefers-reduced-motion: reduce` enabled.
+
+## Keyframe Animations
+- `ease-fade-in-up`: Smooth entrance animation from below.
+- `ease-scale-in`: Spring-physics scale-in entrance with overshoot.
+- `ease-pulse`: Breathing pulse for loading or attention states.
+- `ease-spin`: Continuous rotation for loaders/spinners.
+- `ease-shimmer`: Horizontal shimmer for skeleton loading states.
+
+## Changes
+- `style.css`: 90+ lines with keyframes, utility classes, stagger delays, and reduced-motion override.
+- `demo.html`: Six-panel demo showcasing all five animations.
+- `README.md`: Describes the animation library and accessibility considerations.
+\nFixes #55621\n

+# Breadcrumb CSS Animation & Keyframe Library
+
+## Description
+This PR adds a comprehensive CSS Animation and Keyframe library to the `breadcrumb` component. It provides five production-ready keyframe animations (fade-in-up, scale-in, pulse, spin, shimmer) with stagger delay utilities, all using only `transform` and `opacity` to remain on the GPU compositor thread.
+
+All animations are fully accessible and automatically disable when users have `prefers-reduced-motion: reduce` enabled.
+
+## Keyframe Animations
+- `ease-fade-in-up`: Smooth entrance animation from below.
+- `ease-scale-in`: Spring-physics scale-in entrance with overshoot.
+- `ease-pulse`: Breathing pulse for loading or attention states.
+- `ease-spin`: Continuous rotation for loaders/spinners.
+- `ease-shimmer`: Horizontal shimmer for skeleton loading states.
+
+## Changes
+- `style.css`: 90+ lines with keyframes, utility classes, stagger delays, and reduced-motion override.
+- `demo.html`: Six-panel demo showcasing all five animations.
+- `README.md`: Describes the animation library and accessibility considerations.
+\nFixes #55621\n

+# Carousel CSS Animation & Keyframe Library
+
+## Description
+This PR adds a comprehensive CSS Animation and Keyframe library to the `carousel` component. It provides five production-ready keyframe animations (fade-in-up, scale-in, pulse, spin, shimmer) with stagger delay utilities, all using only `transform` and `opacity` to remain on the GPU compositor thread.
+
+All animations are fully accessible and automatically disable when users have `prefers-reduced-motion: reduce` enabled.
+
+## Keyframe Animations
+- `ease-fade-in-up`: Smooth entrance animation from below.
+- `ease-scale-in`: Spring-physics scale-in entrance with overshoot.
+- `ease-pulse`: Breathing pulse for loading or attention states.
+- `ease-spin`: Continuous rotation for loaders/spinners.
+- `ease-shimmer`: Horizontal shimmer for skeleton loading states.
+
+## Changes
+- `style.css`: 90+ lines with keyframes, utility classes, stagger delays, and reduced-motion override.
+- `demo.html`: Six-panel demo showcasing all five animations.
+- `README.md`: Describes the animation library and accessibility considerations.
+\nFixes #55621\n

+# Code-Inline CSS Animation & Keyframe Library
+
+## Description
+This PR adds a comprehensive CSS Animation and Keyframe library to the `code-inline` component. It provides five production-ready keyframe animations (fade-in-up, scale-in, pulse, spin, shimmer) with stagger delay utilities, all using only `transform` and `opacity` to remain on the GPU compositor thread.
+
+All animations are fully accessible and automatically disable when users have `prefers-reduced-motion: reduce` enabled.
+
+## Keyframe Animations
+- `ease-fade-in-up`: Smooth entrance animation from below.
+- `ease-scale-in`: Spring-physics scale-in entrance with overshoot.
+- `ease-pulse`: Breathing pulse for loading or attention states.
+- `ease-spin`: Continuous rotation for loaders/spinners.
+- `ease-shimmer`: Horizontal shimmer for skeleton loading states.
+
+## Changes
+- `style.css`: 90+ lines with keyframes, utility classes, stagger delays, and reduced-motion override.
+- `demo.html`: Six-panel demo showcasing all five animations.
+- `README.md`: Describes the animation library and accessibility considerations.
+\nFixes #55621\n

+# Drawer CSS Animation & Keyframe Library
+
+## Description
+This PR adds a comprehensive CSS Animation and Keyframe library to the `drawer` component. It provides five production-ready keyframe animations (fade-in-up, scale-in, pulse, spin, shimmer) with stagger delay utilities, all using only `transform` and `opacity` to remain on the GPU compositor thread.
+
+All animations are fully accessible and automatically disable when users have `prefers-reduced-motion: reduce` enabled.
+
+## Keyframe Animations
+- `ease-fade-in-up`: Smooth entrance animation from below.
+- `ease-scale-in`: Spring-physics scale-in entrance with overshoot.
+- `ease-pulse`: Breathing pulse for loading or attention states.
+- `ease-spin`: Continuous rotation for loaders/spinners.
+- `ease-shimmer`: Horizontal shimmer for skeleton loading states.
+
+## Changes
+- `style.css`: 90+ lines with keyframes, utility classes, stagger delays, and reduced-motion override.
+- `demo.html`: Six-panel demo showcasing all five animations.
+- `README.md`: Describes the animation library and accessibility considerations.
+\nFixes #55621\n

+# Image CSS Animation & Keyframe Library
+
+## Description
+This PR adds a comprehensive CSS Animation and Keyframe library to the `image` component. It provides five production-ready keyframe animations (fade-in-up, scale-in, pulse, spin, shimmer) with stagger delay utilities, all using only `transform` and `opacity` to remain on the GPU compositor thread.
+
+All animations are fully accessible and automatically disable when users have `prefers-reduced-motion: reduce` enabled.
+
+## Keyframe Animations
+- `ease-fade-in-up`: Smooth entrance animation from below.
+- `ease-scale-in`: Spring-physics scale-in entrance with overshoot.
+- `ease-pulse`: Breathing pulse for loading or attention states.
+- `ease-spin`: Continuous rotation for loaders/spinners.
+- `ease-shimmer`: Horizontal shimmer for skeleton loading states.
+
+## Changes
+- `style.css`: 90+ lines with keyframes, utility classes, stagger delays, and reduced-motion override.
+- `demo.html`: Six-panel demo showcasing all five animations.
+- `README.md`: Describes the animation library and accessibility considerations.
+\nFixes #55621\n

+# Link CSS Animation & Keyframe Library
+
+## Description
+This PR adds a comprehensive CSS Animation and Keyframe library to the `link` component. It provides five production-ready keyframe animations (fade-in-up, scale-in, pulse, spin, shimmer) with stagger delay utilities, all using only `transform` and `opacity` to remain on the GPU compositor thread.
+
+All animations are fully accessible and automatically disable when users have `prefers-reduced-motion: reduce` enabled.
+
+## Keyframe Animations
+- `ease-fade-in-up`: Smooth entrance animation from below.
+- `ease-scale-in`: Spring-physics scale-in entrance with overshoot.
+- `ease-pulse`: Breathing pulse for loading or attention states.
+- `ease-spin`: Continuous rotation for loaders/spinners.
+- `ease-shimmer`: Horizontal shimmer for skeleton loading states.
+
+## Changes
+- `style.css`: 90+ lines with keyframes, utility classes, stagger delays, and reduced-motion override.
+- `demo.html`: Six-panel demo showcasing all five animations.
+- `README.md`: Describes the animation library and accessibility considerations.
+\nFixes #55621\n

+# Modal CSS Animation & Keyframe Library
+
+## Description
+This PR adds a comprehensive CSS Animation and Keyframe library to the `modal` component. It provides five production-ready keyframe animations (fade-in-up, scale-in, pulse, spin, shimmer) with stagger delay utilities, all using only `transform` and `opacity` to remain on the GPU compositor thread.
+
+All animations are fully accessible and automatically disable when users have `prefers-reduced-motion: reduce` enabled.
+
+## Keyframe Animations
+- `ease-fade-in-up`: Smooth entrance animation from below.
+- `ease-scale-in`: Spring-physics scale-in entrance with overshoot.
+- `ease-pulse`: Breathing pulse for loading or attention states.
+- `ease-spin`: Continuous rotation for loaders/spinners.
+- `ease-shimmer`: Horizontal shimmer for skeleton loading states.
+
+## Changes
+- `style.css`: 90+ lines with keyframes, utility classes, stagger delays, and reduced-motion override.
+- `demo.html`: Six-panel demo showcasing all five animations.
+- `README.md`: Describes the animation library and accessibility considerations.
+\nFixes #55621\n

+# Popover CSS Animation & Keyframe Library
+
+## Description
+This PR adds a comprehensive CSS Animation and Keyframe library to the `popover` component. It provides five production-ready keyframe animations (fade-in-up, scale-in, pulse, spin, shimmer) with stagger delay utilities, all using only `transform` and `opacity` to remain on the GPU compositor thread.
+
+All animations are fully accessible and automatically disable when users have `prefers-reduced-motion: reduce` enabled.
+
+## Keyframe Animations
+- `ease-fade-in-up`: Smooth entrance animation from below.
+- `ease-scale-in`: Spring-physics scale-in entrance with overshoot.
+- `ease-pulse`: Breathing pulse for loading or attention states.
+- `ease-spin`: Continuous rotation for loaders/spinners.
+- `ease-shimmer`: Horizontal shimmer for skeleton loading states.
+
+## Changes
+- `style.css`: 90+ lines with keyframes, utility classes, stagger delays, and reduced-motion override.
+- `demo.html`: Six-panel demo showcasing all five animations.
+- `README.md`: Describes the animation library and accessibility considerations.
+\nFixes #55621\n
